Description
M/A-COM’s AM55-0004 power amplifier/switch integrates a power amplifier and transmit/receive switch in a low cost SSOP package. 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.
