RFPA2235

Single-Stage Power Amplifier 2W,

700MHZ to 2700MHZ

The RFPA2235 is a single-stage InGaP HBT power amplifier. It exhibits excellent

back-off characteristics making it ideal for ultra-linear driver amplifier applications.

The RFPA2235 can also be optimized for use as a small-cell PA output stage. Exter-

nal matching and bias control allows the RFPA2235 to be utilized across various

radio platforms within 700MHz to 2700MHz. The PA2235 offers a robust Class 1C

(>1000V) HBM ESD rating in a compact 4mm x 5mm DFN package.
