Stable oscillator frequency and amplitude with very low interference radiation
Optimal rejection of oscillator and input frequencies at the IF output due to a decoupled
active ring mixer circuit
High interference voltage resistance
High-impedance mixer input, for symmetrical and asymmetrical connections
IF post-amplifier for the UHF IF signal
000 000
IF section
0 Optimal cross-taik rejection
C) Large signal-modulation range
0 Low noise figure with wide minimum over large load-impedance range
