Circuit Description
2.4.1
Mixer-Oscillator block
The mixer-oscillator block includes three balanced mixers (one mixer with an unbalanced
high-impedance input and two mixers with a balanced low-impedance input), two 2-pin
asymmetrical oscillators for the LOW and the MID band, one 4-pin symmetrical oscillator
for the HIGH band, an IF amplifier, a reference voltage, and a band switch.
