... The mixer output signal is amplified by the IF amplifier and output to Pin 1. The IF output is emitter- follower output and output impedance is approximately 50 Ω (480 MHz). 4) PLL oscillation signal output circuit The output circuit is built in to drive the PLL for tuning. This is emitter-follower output and output impedance is approximately 50 Ω. —6— CXA3068N ...
