Description
M/A-COM’s MAAPSS0006 is a high power, high efficiency
linear power amplifier in a miniature FQFP-N 4mm plastic
package. The MAAPSS0006 includes a 2-stage amplifier and
bias control network. Efficiency of the MAAPSS0006 is
optimized for each mode by an on-chip analog control circuit.
The MAAPSS0006 is ideally suited for CDMA and AMPS
handset applications where high linearity and low power
consumption are important transmitter requirements. The
MAAPSS0006 is design to operate with the MD59-0054
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.
