GMRS7001 TECHNICAL DESCRIPTION Page 1 A). GENERAL DESCRIPTION The GMRS7001 GMRS radio is a self-contained transceiver unit with integral antenna intended for use as a general communication tool. It is designed to operate on all 22 channels allocated by the FCC for the licensed FRS & GMRS. This model also features a CTCSS system with 38 pre- defined, user selectable sub-audible tones for channel quieting. The useable range, while dependent upon terrain and other radio propagation principles, is typically five miles. The GMRS7001 uses the maximum transmit power allowed to help ensure the maximum communication range. Features include: 22 FRS, GMRS Channels with 38 CTCSS codes, Digital Receive Volume Control, Channel Monitor, Page and LCD Display. The unit is equipped with an external Headset option connector. Five AAA alkaline batteries that are readily available in retail outlets supply operating power. An automatic power savings feature allows the typical standby battery life to extend to more than 3 days. B). FREQUENCY DETERMINING CIRCUITS The fundamental frequency for both the transmitter and the receiver local oscillators are controlled by a phase lock loop (PLL) circuit Combo1 (Panasonic AN6311, or equipvalent). The frequency of operation of the GMRS voltage controlled oscillator (VCO), composed of Q301,302 operating in cascade is phase locked to a voltage controlled crystal reference (VCXO) operating at 20.95MHz (X202). The VCO is locked to the fundamental of the transmit signal in the transmit mode and is locked to the receive 1 st LO (Fundamental channel frequency minus 21.4MHz) in the receive mode. The crystal reference frequency is shared with the 2 nd LO of 20.95MHz. C). TRANSMITTER CIRCUITS The transmitter amplifies the 0 dBm signal from the VCO to approximately 33 dBm that is fed to the antenna. The transmitter is a three stage amplifier composed of Q1,3 and Q11. The first two stages are operated class A and the final is operated class B in full saturation to help prevent unwanted amplitude modulation. The fundamental transmit signal is fed through an elliptical low pass filter (5-pole, 2 zero) in order to suppress the harmonics to below –50 dBc. The desired frequency modulation of the carrier is accomplished by modulating the current in the VCO directly with the microphone audio signal. The microphone audio is conditioned with a three- pole high pass filter at 300 Hz (Combo1), a hard clipper circuit (Combo1) to GMRS7001 TECHNICAL DESCRIPTION Page 2 limit maximum deviation to +/- 2.5 kHz and a three-pole low pass or splatter filter at 2.8 kHz (IC5C,D). The low pass filter insures that the occupied bandwidth of the FM modulated signal meets FCC requirements under all input conditions. D). RECEIVER CIRCUITS The received signal from the antenna is band limited to 600 Mhz by the transmitter harmonic filter. The desired signal is fed to a low noise amplifier (LNA – Q6) centered from 460 to 470 MHz that provides approximately 10 dB of gain. The output of the LNA is filtered with a Band Pass filter (SF1) with pass-band of 460 to 470 MHz and stopband attenuation of 50 dB. The filtered receive signal is one input to the 1 st mixer (Q8), the other mixer input (1 st LO) is the output of the VCO at the desired channel frequency minus 21.4MHz. The output of the mixer is tuned to the 1 st IF of 21.4 MHz. The 1 st IF is transformer coupled for impedance matching to a X-tal filter centered at 21.4MHz with a bandwidth of +/-3.75Hz. The filtered 1 st IF is fed to the 2 nd mixer input of the multi-function receiver Combo1. The 2 nd LO (20.95 MHz) is generated by VCXO that is the reference frequency for the PLL. The 2 nd mixer output of 450 kHz is filtered through a 4 section ceramic filter that in combination with the 21.4MHz X-tal filter provides approximately 50 dB of adjacent channel attenuation. The 450 kHz 2 nd IF is then amplified, limited and fed to a quadrature detector for FM demodulation. The resulting audio output signal is bandpass filtered from 300 to 3 kHz (Combo1) and amplified to provide 150mW of audio power (IC2). A squelch circuit is provided (Combo1 pins 29 through 30) to mute the receiver noise under low signal conditions. The squelch circuit amplifies and detects noise in a narrow bandwidth at approximately 5 kHz. When the detected noise exceeds a threshold set to trigger at approximately 9 dB SINAD receive signal strength, the audio output is muted. E). TRANSMIT/RECEIVE SWITCH When the radio is in the transmit mode, pin diode switches D2 and D1 are both turned on (representing less than 0.7 ohms). D2 allows the transmit signal to pass to the antenna and D1 shorts one leg of a T matching network (L3, L15 and C4) to ground in the receive path. This results in a parallel tuned circuit high impedance being presented to the transmit signal so that the receive path does not load the transmit signal. In the receive mode, both D2 and D1 are off, resulting in the antenna signal being coupled into the receive LNA through the 50 ohm T matching network and the unwanted load of the transmit final amplifier is reduced to less than 1 pF by D1. F). RADIO CONTROL CIRCUIT A microprocessor (U1) is used to control the transceiver. User stimuli is provided through a tack switch for PTT (push to talk), along with the keypad GMRS7001 TECHNICAL DESCRIPTION Page 3 for channel selection, channel monitor, receive volume, and page. Pressing the PTT switch instructs U1 to switch to the transmit mode. This is accomplished by loading the proper channel counter information through a 3- wire serial link to the PLL IC (Comno1), turning on power to the PLL and VCO, microphone and transmit audio circuits and the transmit RF amplifiers. Pressing the call switch causes the microcontroller to transmit a warbling tone for approximately 3 seconds on the current channel selected that is used to notify another person with GMRS radio that you wish to communicate. Pressing the channel Up/Down buttons (active in receiv…

However, the reported SAR values were well within the limits for both Body Worn and Face held configurations. We considered scaling the results by the amount of “droop” but considered this unacceptable as a first choice. Therefore, we asked for a retest using a DC Power Supply in place of batteries. This retest was performed for the worse case Body Worn configuration (20mm). The resulting power drift was recorded at 0.06dB yielding a SAR value of 1.075 W/kg for a 50% duty factor. By examining this new result, we verified the worst case SAR configuration did comply with the limits, therefore, we could reliably scale the additional values to verify compliance. An additional plot showing the described result is being submitted along with a dipole calibration plot for this requested test. A photograph of the test set-up which shows the EUT, phantom, and DC Power Supply is also included as part of the submission. Based on the results of the retest, this EUT does comply with the SAR limit of 1.6 W/kg. We will show on the “Grant” the worst case Body Worn Configuration value at 1.075 W/kg and the worst case Face Held configuration scaled up to 1.315 W/kg. These values meet the limits criterion. Very truly yours, Frank (for) Sid Sanders
