ANADIGICS is introducing two 3-stage power
amplifiers designed for high performance in Quad
Band Applications. The amplifiers are packaged in
a very small 6 x 8mm module. The output power is
controlled by changing the voltage applied to the
VAPC pin for each amplifier. The part is shut down by
removing the regulated supply voltage.
InGaP HBT Technology
+35dBm GSM Output Power at 3.5V
+32.5dBm DCS/PCS Output Power at 3.5V
35% GSM850 PAE (Class 5)
50% GSM850 PAE (Class 4)
55% GSM900 PAE
50% DCS/PCS PAE
Low Profile 1.4mm Package
Small footprint 6 x 8mm SMT Package
GPRS Capable (class 12)
APPLICATIONS
GSM850/GSM900/DCS/PCS Handsets
Dual/Tri/Quad Band PDA
The amplifier is manufactured using an advanced
InGaP HBT technology, offering state of the art
reliability, temperature stability and ruggedness.
Passive matching networks are integrated to
provide internal matching to 50Ω at both the RF
inputs and outputs. Internal DC blocks are provided at the RF inputs.

Note 1: The VAPC must be pulled down to 0.45V with a low impedance. If VREG_GSM & V REG_DCS/PCS inputs
are connected then both VAPC inputs must be pulled down to 0.45V to disable both power amplifiers.
