Description
M/A-COM’s MAAPSS0003 is a high power, high efficiency
linear power amplifier in a miniature FQFP-N 4mm plastic
package. The MAAPSS0003 includes a 2-stage amplifier and
bias control network. Analog signals control output power and
power-off for active and standby modes.
The MAAPSS0003 is ideally suited for TDMA and CDMA
handset applications where high linearity and low power
consumption are important transmitter requirements. The
MAAPSS0003 is design to operate with the MD59-0062
Upconverter/Driver IC.
The MAAPSS0003 is fabricated using M/A-COM’s
iHBT
HBT process. The process utilizes the InGaP/GaAs materials
system for reduced performance variation over temperature,
high reliability and improved manufacturability.

±
1.25MHz
offset from the carrier frequency.
