Description
M/A-COM’s AM55-0004 power amplier/switch integrates a power amplier and transmit/receive switch in a low cost SSOP package. The power amplier delivers +24 dBm of linear power with high efciency 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 amplier/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 amplication 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 performance and……
