Summary: 
A wideband monolithic lossy match power amplifier having an LPF/HPF-combined interstage network has been developed. As an interstage network, it employs an LPF (Low-Pass Filter) including FET's drain capacitance, an HPF (High-Pass Filter) comprised of a dc blocking capacitor and a drain bias circuit, and a constant-resistance network for wideband impedance matching and transformation. With the use of this interstage network, a wide bandwidth of 6 to 16.5 GHz and an output power of 30.40.9 dBm have been achieved.
