CIRCUIT DESCRIPTIONS • FRONT-END TRANSMISSION UNIT • PRE-AMPLIFIER The pre-amplifier consists of Q807 & Q808. The VCO output signal is applied to pre-amplifier (Q807 & Q808), to obtain a level above 14dBm, while operating in the frequency range of 135MHz to 174MHz. The T5V supplies a 5V to pre-amplifier Q810 & Q809 are turned on by T5V. -
