    TP620 Service Manual signal can be offered to the last power amplifier (Q501 RD07) for final power amplification. After being processed by a set of amplifiers at several levels, the Tx signal will complete the output impedance match through a microstrip line at the output terminal of the last power amplifier, through which the output power loss caused by impedance mismatch can be avoided.
  • Page 7 TP620 Service Manual • Rx Circuit RF Part The high frequency signal from low-pass filter passes the front stage electrically tunable band-pass filter controlled by electric level and output by DAC (U301 PIN29) so as to filter out the out-of-band interference signal, sending effective band-pass signal into the low noise amplifier (Q505).
