A matching network with benefit of realization and wide bandwidth for millimeter-wave power amplifiers is proposed. With the proposed matching network, the characteristic impedance of the λ/4 transformersare increased and the length of the λ/4 transformers are reduced. A 71-80 GHz medium power power amplifier using 4-mil 0.15-μm HEMT is demonstrated based on the proper matching network. A 18.8-dBm output power with 10.7% peak PAE has been achieved and reveals that this matching is suitable for millimeter-wave power amplifier designs.
