PRODUCT DESCRIPTION
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
V
APC
pin for each amplifier. The part is shut down by
removing the regulated supply voltage.
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 pro-
vided at the RF inputs.
