20-30GHz broadband MMIC power amplifiers with compact flat gain PHEMT cells

20-30GHz band MMICs have been successfully developed using two types of novel compact size flat gain PHEMT cells that have flat maximum available gain and sufficient stabilities over a wide frequency range of 20-30GHz. One type is a feedback type. The other has an equalizer circuit at the gate of a...

Summary:20-30GHz band MMICs have been successfully developed using two types of novel compact size flat gain PHEMT cells that have flat maximum available gain and sufficient stabilities over a wide frequency range of 20-30GHz. One type is a feedback type. The other has an equalizer circuit at the gate of a PHEMT. The MMIC delivers gains of over 18dB and P1dB of over 22dBm. These results show this method is very effective in designing broadband MMICs.
