UHF2 Receiver

2.9.1

Receiver Front-End

The RF signal is received by the antenna and applied to a low-pass filter. For UHF, the filter consists 
of L101, L102, C102, C103, C104. The filtered RF signal is passed through the antenna switch. The 
antenna switch circuit consists of two PIN diodes(CR101 and CR102) and a pi network (C106, L104 
and C107).The signal is then applied to a varactor tuned bandpass filter. The UHF bandpass filter  
comprises of L301, L302, C302, C303, C304, CR301 and CR302. The bandpass filter is tuned by 
applying a control voltage to the varactor diodes(CR301 and CR302) in the filter.

The bandpass filter is electronically tuned by the DACRx from IC404 which is controlled by the 
microprocessor. Depending on the carrier frequency, the DACRx will supply the tuned voltage to the 
varactor diodes in the filter. Wideband operation of the filter is achieved by shifting the bandpass 
filter across the band.

The output of the bandpass filter is coupled to the RF amplifier transistor Q301 via C307. After being 
amplified by the RF amplifier, the RF signal is further filtered by a second varactor tuned bandpass 
filter, consisting of  L306, L307, C313, C317, CR304 and  CR305. 

Both the pre and post-RF amplifier varactor tuned filters have similar responses. The 3 dB bandwidth 
of the filter is about 50 MHz. This enables the filters to be electronically controlled by using a single 
control voltage which is DACRx .

The output of the post-RF amplifier filter which is connected to the passive double balanced mixer 
consists of T301, T302 and CR306. Matching of the filter to the mixer is provided by C381. After 
mixing with the first LO signal from the voltage controlled oscillator (VCO) using low side injection, 
the RF signal is down-converted to the 44.85 MHz IF signal.
