The product of the integrating circuit is fed to IC501 pin 25. PA G E 6 Charge Pump and Loop Filter Transistors Q2, Q4, Q10, and associated resistors and capacitors form the charge pump and loop Filter. The phase detector output from IC1 pins 15 and 16 are combined by the charge pump to produce a 0 to 15V tuning voltage signal. The signal is filtered by the loop filter (R13, C16 and C17) to remove any residual reference Frequency harmonics from the signal. After filtering the signal is applied to the voltage controlled Oscillator module. DC to DC Converter The DC-to-DC converter converts the +7.5 V to a 14-16 V supply. This is used to provide the Tuning voltage for the VCO. A wide voltage range is required to allow for the wideband operation of the radio. Q506 to Q508, and associated components, form a 200kHz oscillator. The output of the oscillator is rectified and filtered by D503, D506, C548 and C11. The resultant 16VDC is passed to R544 and then becomes the supply rail for the charge pump. Dual modulus prescaler The prescaler divides the VCO frequency by 64 or 65. Transmitter The transmitter comprises: VCO Buffer PA Module Amp PAGE 7 RF LPF ANTENNA SWITCH Automatic Power Control Buffer When the radio is in transmit mode the diode D2 is forward biases enabling the modulated RF signal from the VCO to pass to the buffer/pre-amplifier Q21 and Q22 and associated components. The output signal is passed from Q22 to IC5 via a matching network consisting of Inductor L7 and C73. PA module The signal is then amplified for transmission by IC5, which is a power amplifier module. Low pass filter The amplified RF signal is passed through the stripline coupler and is fed to the harmonic low pass filter, comprising L12 to L15 and C94-C98 and then to the antenna connector (ANT). The stripline coupler provides a sample of the RF signal for the automatic power control. Antenna Switch When transmitting, the diodes D5 and D6 are forward biased, allowing the RF to pass to the antenna. D6 is shorted to ground which makes L11 look open circuit (1/4 wave tuned stub). This prevents the TX signal from passing to the receiver stage. Automatic power control (APC) circuits The automatic power control contains the stripline coupler, diode D4, variable resistor RV1, U4A and transistors Q19 and Q23. The RF signal present in the coupler is rectified by D4, to produce a DC voltage. This DC voltage is passed to one input of IC4A, which is a differential amplifier. In transmit mode a DC reference level for U4A is supplied by the potential divider R34/R35. The reference level and the detected lev…

FCC ID: L9N-7085-VE (The following will be placed in the Instruction Manual) MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS & USERS Use only manufacturer or dealer supplied antenna. Antenna Minimum Safe Distance: 46 cm. Antenna Gain: zero dBd referenced to a dipole. The Federal Communications Commission has adopted a safety standard for human exposure to RF (Radio Frequency) energy which is below the OSHA (Occupational Safety and Health Act) limits. Antenna Mounting: The antenna supplied by the manufacturer or radio dealer must not be mounted at a location such that during radio transmission, any person or persons can come closer than the above indicated minimum safe distance to the antenna i.e. 46 cm. To comply with current FCC RF Exposure limits, the antenna must be installed at or exceeding the minimum safe distance shown above, and in accordance with the requirements of the antenna manufacturer or supplier. Base Station Installation: The antenna should be fixed- mounted on an outdoor permanent structure. RF Exposure compliance must be addressed at the time of installation. Antenna Substitution: Do not substitute any antenna for the one supplied or recommended by the manufacturer or radio dealer. You may be exposing person or persons to excess radio frequency radiation. You may contact your radio dealer or the manufacturer for further instructions. WARNING: Maintain a separation distance from the antenna to a person(s) of at least 46 cm. You, as the qualified end-user of this radio device must control the exposure conditions of bystanders to ensure the minimum separation distance (above) is maintained between the antenna and nearby persons for satisfying RF Exposure compliance. The operation of this transmitter satisfies the requirements of General Population Exposure Environment. Transmit only when person(s) are at least 46 cm distance from the properly installed, externally mounted antenna.

For transmitters designed to operate with a 12.5 kHz channel bandwidth, any emission must be attenuated below the power (P) of the highest emission contained within the authorized bandwidth as follows: (1) On any frequency from the center of the authorized bandwidth fه to 5.625 kHz removed from fه: Zero dB. (2) On any frequency from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more than 5.625 kHz but no more than 12.5 kHz: At least 7.27 (fd - 2.88 kHz) dB. (3) On any frequency removed from the center of the authorized bandwidth by a displacement frequency (fd in kHz) of more than 12.5 kHz: At least 50 + 10 log (P) dB or 70 dB, whichever is the lesser attenuation. 90…
