2. vertical antenna No.2 (not in picture) (PCB)
3. Pin-Diode (Diversity switch)
4. bias for antenna 1 or 2
5. main power amplifier
6. BP network (( .42 ))
7. RX LNA
8. LMX3161 single chip radio transceiver, contains phase locked loop
(PLL), transmit and receive functions.
The transmitter includes a frequency doubler, and a high frequency buffer. The receiver consists of a 2.0 GHz low noise
mixer, an intermediate frequency (IF) of 110 MHz. more on http://www.national.com/pf/LM/LMX3161.html
