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
