Page 3: Circuit Description
CIRCUIT D E S C R I P T I O N 1) Receiver System 1. Preamp, Mixer Circuit The signal from the antenna is passed through a low -pass filter and input to L211. The signal from L211 is led to the base o f Q 208. The signal from Q 208 is led to the triple band pass filter (L212, L213, L214), and gets the high im age rejection ratio. -
Page 4: Pll Circuit
2. TX Amp. Circuit The signal from V C O is amplified by T X , RX wide band LO amplifier Q 207. The signal from Q207 is passed through the transmission/reception selector, and amplified by Q206 and Q 202. The PA unit is driven at mW driving power. -
