250 mW Power Amplifier with T/R and Diversity Switches
2.4 - 2.5 GHz
Features
Highly Integrated Power Amplifier With T/R and
Diversity Switches
Operates Over 2.7 V to 6 V Supply Voltage
High Linear Output Power (P
: +24 dBm)
1dB
Individual Gate Control for Each Amplifier Stage
Low Cost SSOP-28 Plastic Package
Description
M/A-COM’s AM55-0003 is a GaAs power amplifier with
integrated transmit/receive and an antenna diversity switch
in a low cost SSOP 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 and diversity switches achieve good insertion loss and
isolation without degrading the overall linearity. The
switches can be controlled with CMOS logic levels.
The AM55-0003 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. This power amplifier
can be combined with a transceiver IC (MD58-0001 or
MD58-0002) to form a complete RF front end.
M/A-COM's AM55-0003 is fabricated using a mature
0.5-micron gate length GaAs process. The process features
full passivation for increased performance and reliability.
