■ RF frequency plan
RF frequency plan is shown below. The VCO operates at the channel frequency multiplied by
two or four depending on the frequency band of operation. This means that the baseband mod-
ulated signals are directly converted up to the transmission frequency and the received RF sig-
nals directly down to the baseband frequency.
