D passes through the buffer amplifier 01049 25C5555ZD and TX RX switch D1026 DAN222 The signal from D1026 DAN222 is amplified by Q1060 25C5555ZD and 01064 RDO1MUS1 and ultimately applied to the final amplifier Q1069 RDO7MVS1 which increases the signal level up to 5 watts output power The transmit signal then passes through the antenna switch D1039 RLS135 and is low pass filtered to suppress away harmonic spurious radiation before delivery to the anten na Automatic Transmit Power Control RF power output from the final amplifier is sampled by C1275 C1279 and is rectified by D1043 HSM88WA The resulting DC is fed through the Automatic Power Con troller Q1074 NJM2125F thus allowing control of the power output Transmit Inhibit When the transmit PLL is unlocked pin 7 of PLL chip 01041 MB15A01PFV1 goes to a logic low The result ing DC unlock control voltage is switches off TX inhibit switches Q1053 DTC144EE and 01055 DTA143EE to disable the supply voltage to transmitter RF amplifiers Q1060 25C5555ZD disabling the transmitter Spurious Suppression Generation of spurious products by the transmitter is min imized by the fundamental carrier frequency being equal to the final transmitting frequency Additional harmonic suppression is provided by a low pass filter consisting of L1025 L1027 amp L1029 and C1271 C1280 C1282 C1285 C1289 amp C1293 resulting in more than 60 dB of harmonic suppression
