The power ampliﬁer delivers +24 dBm of linear power with high efﬁciency and can be operated at supply voltages as low as 2.7 V. It is ideally suited for QPSK or other linearly modulated systems in the 1.8 to 2.0 GHz frequency band. The power ampliﬁer/switch is fully monolithic and requires only one output capacitor for power match. The T/R switch achieves good insertion loss and isolation without degrading the overall linearity. The AM55-0004 is ideally suited for final stage power ampliﬁcation in linear TDD systems. The integrated switch is convenient for duplexing. The AM55-0004 can also be used as a driver stage for high power systems. Typical applications include Japanese PHS systems or PCN/PCS transmit chains. M/A-COM’s AM55-0004 is fabricated using a mature 0.5-micron gate length GaAs process. The process features full passivation for increased perform...
