THEORY OF OPERATION

5.2

Voltage Controlled Oscillator (VCO)

(

Refer to Figure 2-6 and the VHF Voltage Controlled Oscillator schematic diagram)

The VCOB IC (U3801), shown in Figure 2-6, in conjunction with the Fractional-N synthesizer 
(U3701) generates RF in both the receive and the transmit modes of operation. The TRB line 
(U3801 pin 19) determines which oscillator and buffer are enabled. A sample of the RF signal from 
the enabled oscillator is routed from U3801 pin 12, through a low pass filter, to the prescaler input 
(U3701 pin 32). After frequency comparison in the synthesizer, a resultant CONTROL VOLTAGE is 
received at the VCO. This voltage is a DC voltage typically between 3.5V and 9.5V when the PLL is 
locked on frequency.
