Low Cost QSOP-28 Plastic Package
Description
M/A-COM’s AM55-0015 is a GaAs power amplifier with an
integrated transmit/receive switch in a low cost QSOP-28
plastic package. The power amplifier delivers +24 dBm of
linear power with high efficiency and can be operated with
voltages as low as 2.7 volts. The power amplifier switch is fully
monolithic. The T/R switch achieves good insertion loss and
isolation without degrading the overall linearity. The switch can
be controlled with CMOS logic levels.
The AM55-0015 is ideally suited for QPSK, BPSK or other
linearly modulated systems in the 2.4 GHz ISM frequency band.
It can also be used in GFSK systems where levels of +25 dBm
are required. Typical applications include WLAN and wireless
portable data collection.
M/A-COM's AM55-0015 is fabricated using a mature 0.5
micron gate length GaAs process. The process features full
passivation for increased performance and reliability.
