SDB670 – SERVICE MANUAL TNM-M-E-0032 reduced by approximately 20 dB in a single step when D415/D416 are turned on by the FPGA via RX-GAIN. The output of the AGC circuit contains a matching network for the following crystal filter Z401, which in turn is matched to a dual current amplifier U402. The crystal filters provide part of the required selectivity for rejection of close in unwanted signals.
SDB670 – SERVICE MANUAL 5.3.3.2 TNM-M-E-0032 Power Control Output power is stabilised by a power control feedback loop. A printed circuit transmission line, L521, R557, C557, D506 and associated components comprise the power detector. Comparator U502A and associated components provide the power setting and control functions. Forward and reverse power is sampled by the power detector and applied as a DC voltage to the inverting input of the comparator.
