PRODUCT DESCRIPTION
The AWT6521 Power Amplifier module is designed
for 3G/4G handsets, smartphones, modems and
modules operating in LTE, WCDMA/HSPA and CDMA/
EVDO modes. The module includes two separate
InGaP HBT amplifier chains - one to support 850/900
bands, the other for 1700/1900/2100MHz bands. An
innovative design allows the module to switch output
among as many as 5 different frequency bands. Both
the input and output RF ports are internally matched
to 50 Ω. The AWT6521 offers improved efficiency and
low quiescent current, and includes integrated daisy
chained couplers to simplify board design and layout.
