Qyt Kt7900d Service Manual 100%

Because the transceiver chip only outputs a few milliwatts, the signal is passed through a driver stage to a final RF Power Amplifier module or discrete FET network. This stage boosts the signal to the rated 20-25W output. A low-pass filter (LPF) network follows the PA to suppress harmonics before the signal reaches the antenna.
