Overview CNI-803D, RPM(Radio Packet Modem), is a digital data communication equipment in accordance with RD-LAP19.2 and MDC4800 specification. CNI-803D uses the frequency ranges from 806MHz to 821Mhz for transmission, and from 851MHz to 866MHz for reception. This modem enables you to make data communication in two-way, and it also helps you to enjoy various types of data services with full mobility due to support for roaming. With ‘Interface Connector’ you can apply this modem to many kinds of machines to use ‘RD-LAP and MDC Asynchronous Serial Communication (NCL)’ protocol for communication, and NCL commands enable you to monitor the operation during communication. 3 !

Circuit guide A. RF circuit CNI-803D circuit is composed of five parts such as power supply, antenna, synthesis/modulation of frequency, transmission and reception. 1 power supply Power supply is composed of voltage regulator and switching part. Voltage regulator generates 3V of power supplied from VBB when the control of RF_EN switch is turned on. When RF_EN is high, RF_VCC is regulated with 3V, and RF_VCC is supplied to PLL IC, VCTCXO, OP-Amp(IC102), VCO, and Drive Amp(Q104). When RX_EN is low, RX_VCC is turned on by Q202, and RX_VCC (3V) is supplied to LNA , M IXE R , IF AMP and IF IC . When TX_EN is low, TX_VCC is turned on by Q201, and TX_VCC (3V) is supplied to Buffer Amp(Q105) and OP-Amp(IC104). The switch between TX mode and RX mode can be achieved by control of RX_EN(Q202) and TX_EN(Q201). 2 Antenna Antenna part is composed of antenna matching circuit, BPF, and Rx/Tx signal isolation circuit. CNI-803D adapts  /4 WHIP antenna to match to mid range frequency of communication. TX/RX signal isolation circuit isolates signals of communication and is composed of switching diode and inductor. The signals received from antenna meet the send/receive path and then D1 is turned on and the signals proceed only to receiving path. In receiving mode, signals from TX Power Amp can not go through RX path because D101 is off. (refer to RF circuit diagram) 3 Frequency synthesizer and modulator Frequency synthesizer consists of PLL part, VCO module and pre-modulation filter. The PLL part is composed of phase detector, loop filter, and 12.6Mhz VCTCXO VCO module generates 806~821Mhz frequencies in accordance with the voltage which is from charge pump of PLL to loop filter. Programmable Divider in PLL makes the VCO output frequency to any channel value according to the frequency data from Logic CPU. Phase detector gets low and high frequencies from comparison of phase. Loop filter filters the frequencies to get a value of voltage. The voltage is input to VCO to achieve phase lock process. Modulation is completed when modem IC signal of Logic part is input to VCO and authorized. 4 Receiver 5 Receiver filters and amplifies RF signal through SAW filter and LNA RX part is double super heterodyne type, and consists of LNA, LPF, Mixer, SAW filter and IF IC part. There happens RX signal from antenna and the signal is low-noise- amplification (LNA) through SAW filter and LNA, and it comes to 2nd IF 455KHz via 2nd X-TAL44.545MHz. SAW filter rejects Image frequency(RX ± 2*IF) generated from 1’st Mixer while receiving. For example, if the input channel is 858Mhz, the output frequency would be 45Mhz from mixer while local frequency is 813Mhz. However, if SAW filter will not filter the image frequency of 858 ± 2*IF, S/N would be worse with 45Mhz(813-768=45) of noise. And SAW filter should filter to prevent local frequency becoming spurious through LNA and reverse path. LNA amplifies and sends the faint signal from antenna to mixer, and mixer TR mixes and generates 1st IF with frequency from antenna. IF comes from mixer. And IF contains inter-modulation product component. MCF removes that product component. So clean IF(45MHz) can be inserted to IF IC. 2nd local frequency ent…

The EUT was placed inside the temperature chamber. The DC leads, RF output cable, exited the chamber through an opening After the temperature stabilized for approximately 20 minutes, the frequency of the output signal was recorded from the counter. 9.2Test Equipment Temperature Chamber, -50C to +100C Hewlett Packard 5383A Frequency Counter Tektronix 2784 Spectrum Analyzer Goldstar DC Power Supply, GR303 9.3Test Results Refer to the test data below.

The transmitter was continuously transmitting a modulated signal (FSK, 2400 bits/sec.). The generator was generating FM signal (1 kHz tone, 12.5 kHz deviation). Several plots were made on the FM demodulator output with the EUT turned ON and OFF. 11.2Test Results ResultsNot Applicable A1365 Adams Ct.

Dashes “-” are used to indicate that there is no limit under the guideline. 12.2Test Procedure The test was performed at 815 MHz. The antenna was placed on a 0.8m wooden table on open site. The antenna was connected to the EUT. EUT output power was measured at RF output connector. EUT has 0.47W ERP power output. The sensor of the field strength meter was moved around the antenna to obtain the maximum reading of the field strength meter. The measurements were performed at the distance 0.1m to 1m from the antenna. 12.3 Field Strength Calculations The field s…
