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.

1. Spectral output is tested under the following conditions:
Modulation scheme is π/4 DQPSK with a bit transfer rate
of 384 kB/sec and a root Nyquist filter with ␣ = 0.5 per
RCR STD-28. The spectrum analyzer settings are as follows:
Resolution bandwidth: 10 kHz
Video bandwidth: 100 kHz
Sweep time: 5 seconds
2. This chart documents the modulated output power delivered
for a fixed adjacent channel interference (ACI) rejection of 55
dBc at a 600-kHz offset.
