SPA-1426Z
0.7GHz to 2.2GHz 1W InGaP HBT AMPLIFIER
RFMD’s SPA-1426Z is a high linearity single-stage class A Heterojunction Bipolar
Transistor (HBT) power amplifier. The SPA-1426Z is made with InGaP-on-GaAs
device technology and fabricated with MOCVD for an ideal combination of low cost
and high reliability. It is well suited for use as a driver stage in macro/micro-cell
infrastructure equipment, or as the final output stage in pico-cell infrastructure
equipment. It features an input power detector, on/off power control, ESD protec-
tion, excellent overall robustness and a hand reworkable and thermally enhanced
SOF-26 package.
