1 Circuit Description 1 SINGLE CHIP TRANSCEIVER RDA1846 is one of the main components of the walkie-talkie. The RDA1846 is a highly integrated single-chip transceiver for Walkie Talkie applications. It totally realizes the translation from RF carrier to voice in the RX path and from voice to RF carrier in the TX path, requiring only one micro controller. Figure 1 RDA1846 Block Diagram 2 Receiver (RX) Front end The RX signal from the antenna is passed through the LPF and antenna SW (D1, D4 and D5), and is sent to pin 15 of IC5 (RDA1846) to be demodulated and to output Figure 2 Receiver Diagram 2 Audio signal processing The demodulated audio signal output from IC5 (RDA1846) passes through the volume potentiometer to be adjusted, and then goes to the audio power amplifier IC1 (TDA2822). Squelch circuit Output from pin 26 of IC5 (RDA1846) is sent to the MCU. MCU identifies the level of the noise and controls the squelch. Audio power amplifier The BTL type audio power amplifier circuit consists of IC1 and its peripheral components. Base electrode of Q38 is the control terminal. High level: Open; Low level: Close. The Rx audio signal, voice alert signal, alert tone signal and warning tone signal are collected and passed through the audio power amplifier where they are amplified and output to drive the speaker. The volume of the warning tone is not controlled by the preset volume level of the radio. Speaker impedance: 16Ω. Note: Any terminal of the speaker should not be grounded! CTCSS/DCS signal processing CTCSS/DCS signal output from pin 32 of IC5 (RDA1846) is sent to MCU for decoding. 3 Transmitter (TX) Figure 3 Transmitter Diagram TX power amplification The modulated RF signal from IC5 (RDA1846) is amplified by Q4, Q3 and Q12, and is sent to Q11 for power amplification. Output power of Q11: 5.0W. Grid bias of Q12 and Q11 is controlled by the APC circuit. Through changing the grid bias voltage, the Tx output power can be controlled conveniently. 3 APC (Automatic Power Control) R167, R168 and R169 are used to test the power amplification current. IC3A is the sampling amplifier for the power amplification current. IC3B is the power comparator amplifier. If the Tx output power is too high, the power amplification current and IC3A output will increase; IC3B output voltage will decrease, so the offset voltage added to Q11 and Q12 will also decrease, which causes the Tx output power to be lowered, and vice versa. Thus the Tx output power can keep stable under different working conditions. MCU can set the power through changing the voltage input to IC3B. Tx voice signal processing MIC signal passes through the internal/external MIC switch circuit and is sent to pin 11 of IC5 (RDA1846) for carrier modulation. 4 Frequency Synthesizer The 12.8MHz reference frequency signal provided by X1 is divided by the internal reference frequency divider of IC5 (RDA1846), and is then sent to the internal phase comparator of IC5, where the signal is compared with the signal divided by the fractional frequency divider of internal VCO. Then the output signal is used to control the internal VCO, enabling the frequency to reach the set value. 5 Power Supply The radio uses 7.4V, 1700mAh Li-Poly battery. The Tx power amplification circuit (Q11 and Q12) and the Rx audio power amplifier (IC1) directly adopt the battery for power supply. Power of other circuits is supplied by 5V or 3.3V regulated voltage. IC7:3,3V LDO, 3M power supply, and supplies power for RD1846 and MCU IC8:5V LDO,5R and 5T power supply Q29: 5T switch (controlled by MCU) 5T: supply power for the front end of transmitter 6 MCU Unit MCU Unit controls the operation of every unit to realize all functions of the CU560-2. Communication with external PC State data access Control PLL for the generation, receiving and transmitting of local oscillation frequency Access to the current channel state Control LED status indicator Control power supplied condition of every unit Detect action of every function key Produce CTCSS signal Produce DCS signal Produce power controlled signal Finish CTCSS decoding Finish DCS decoding Squelch detection and control Control voice prompt content 4 Memory (FLASH) Channel data, CTCSS/DCS data and other function setting data and parameter adjustment data. CTCSS/DCS signal coding and decoding: CTCSS/DCS signals from MCU (pin17 output) are sent to pin32 of IC5 for modulation respectively. CTCSS/DCS signals from IC5 are sent to MCU(pin52) for decoding, and then MCU test if there are CTCSS/DCS signals with the same setting of the station to decide whether open the speaker or not. CTCSS (continuous tone control squelch system, hereinafter referred to as CTCSS), is a kind of squelch control system with modulation on carrier and continuous sub-audio signals as pilot tone. If CTCSS function is set, the call is available only at the same CTCSS frequency of both receiving and transmitting parties to avoid the disturbance of other signals. The station has 39 groups of standard CTCSS frequency for your selection, such as Table 1.

If DCS function is set, the speaker is available only when receiving the same DCS code to avoid the disturbance of useless signals. The station has 83 kinds of standard codes including positive and inverse code for your selection, such as Table 1 DCS signals produced by MCU (PWM waveform) are sent to IC5 for modulation.

Federal Communications CommissionDA 13-431 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended Promotion of Spectrum Efficient Technologies on Certain Part 90 Frequencies ) ) ) ) ) ) ) WT Docket No. 99-87 RM-9332 ORDER Adopted: March 15, 2013Released: March 18, 2013 By the Chief, Wireless Telecommunications Bureau, Chief, Public Safety and Homeland Security Bureau, and Chief, Office of Engineering and Technology: 1.Introduction.In this Order, we grant in part and deny in part a Petition to Delay Indefinitely Implementation of Section 90.203(j)(5) of the Commission’s Rules filed by Ritron, Inc. (Ritron) on September 21, 2012. 1 Pursuant to Section 90.203(j)(5) of the Commission’s rules, the Commission no longer accepts applications for certification of Part 90 private land mobile radio (PLMR) equipment in the 150-174 MHz and 450-512 MHz bands that cannot operate in a 6.25 kHz mode or with equivalent efficiency. 2 Ritron requests that implementation of this requirement be delayed indefinitely. We conclude that the requirement should be waived only until January 1, 2015. 2.Background.In 1995, the Commission adopted rule changes to promote the efficient use of the PLMR service and facilitate the introduction of advanced technologies. 3 To promote the transition to a more efficient narrowband channel plan, the Commission provided, inter alia, that “only increasingly efficient equipment” would be approved. 4 The Commissiondid not set a date after which it would no longer approve equipment with a wideband (25 kHz) mode, or after which such equipment could no longer be manufactured or used. 5 The Commission contemplated that, as systems reached the end of their service life and new radios were needed, users would migrate to the narrower bandwidth multi-mode radios in order to avoid the adjacent-channel interference that could occur from systems using the adjacent narrowband channels. 6 3.Subsequently, the Commission determined that the 1995 rules failed to provide adequate incentive to realize the Commission’s spectrum efficiency goals in these bands, and stronger measures 1 SeePetition to Delay Indefinitely Implementation Section 90.203(j)(5) of the Commission’s Rules (filed Sept. 21, 2012) (Petition). 2 See47 C.F.R. § 90.203(j)(5). 3 SeeReplacement of Part 90 by Part 88 to Revise the Private Land Mobile Radio Services and Modify the Policies Governing Them, Report and Order and Further Notice of Proposed Rule Making, PR Docket No. 92-235, 10 FCC Rcd 10076, 10077 ¶ 1 (1995). 4 Id.at 10081 ¶ 7. 5 Id.at 10100 ¶ 40. 6 Id. Federal Communications CommissionDA 13-431 2 would be required to bring about a timely transition to narrowband technology. 7 The Commission therefore amended the rules to provide that, by January 1, 2013, Industrial/Business and Public Safety Radio Pool licensees in the 150-174 MHz and 421-512 MHz bands must migrate to 12.5 kHz channel bandwidth or utilize a technology that achieves equivalent efficiency. 8 4.The Commission also adopted interim deadlines to facilitate this transition to narrowband technology. Among other rules, the Commission provided that, beginning January 1, 2011, it would no longer accept applications for certification of equipment that cannot operate in 6.25 kHz mode or with equivalent efficiency. 9 In 2010, the Commission temporarily waived this requirement until January 1, 2013, 10 but stated, “If 6.25 kHz standards still are not in place at that date, interested parties may request a further extension.” 11 5.Ritron, a manufacturer of wireless products, contends that standards for 6.25 kHz technology are not yet in place and that other issues exist that justify delaying implementation of mandatory 6.25 kHz certification by manufacturers.Ritron states that no one 6.25 kHz equipment standard exists and that, in the Industrial/Business sector of the market, two incompatible and proprietary technologies have emerged. 12 Italso argues that 6.25 kHz equipment is still unduly expensive. 13 Finally, Ritron asserts that using the equipment authorization process to facilitate the transition to narrowband technology has been largely unsuccessful. 14 Itconcludes that the implementation of Section 90.203(j)(5) should be delayed until (a) a real need has been established for additional PLMR frequencies beyond those created by the transition to 12.5 kHz channels; (b) the benefits of 6.25 kHz outweigh the associated research and development, manufacturing, and product costs; and (c) a standard has emergedfor a more cost-effective voice compressor/decompressor (vocoder). 15 6.The Wireless Telecommunications Bureau, Public Safety and Homeland Security Bureau and the Office of Engineering and Technology sought comment on Ritron’s request. 16 We asked commenters to address whether the public interest would be served by further delaying implementation of 7 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended,Second Report and Order and Second Further Notice of Proposed Rulemaking, WT Docket No. 99-87, 18 FCC Rcd 3034, 3038 ¶ 12 (2003). 8 See 47 C.F.R. § 90.209(b)(5). The January 1, 2013 deadline for converting to 12.5 kHz technology has been waived for licensees in the 470-512 MHz segment of the UHF band (the T-Band). SeeImplementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Order, WT Docket No. 99-87, 27 FCC Rcd 4213 (T-Band Order), on recon., Order on Reconsideration, 27 FCC Rcd 14770 (WTB/PSHSB/OET 2012). 9 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended,Third Report and Order, WT Docket No. 99-87, 22 FCC Rcd 6083, 6090 ¶ 16 (2007) (Third Report and Order). 10 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Order, WT Docket No. 99-87, 25 FCC Rcd 8861, 8866 ¶ 11 (2010) (Order). 11 Id.at 8866 n.41. 12 …
