RF AMPLIFIERS

EL1AT118

Frequency modulated signals from the master oscillator are applied through buffer amp A6400 to

module A6500. Signals entering A6500 are applied to Q6501 and Q6502 for amplification. The tuning

circuits, adjusted mechanically by the gear train, tune rf driver Q6502 for maximum gain which

provides driving power for the final rf amp stages.

Amplified fm from the push-pull network of Q6503 and Q6504 is coupled through transformer T6505

and applied to module A4500 and the rf detector in module A6500.
