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. 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 reliability.
