Features

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.
