RFMD's RFPA1702 is a high linearity power amplifier in a surface mount package
designed for use in transmitters that operate at frequencies between 17.7GHz to
19.7GHz. It provides 25dB of small-signal gain. This power amplifier is optimized for
linear operation with an output third order intercept point (OIP3) of ≥ +40.0dBm.
The RFPA1702 is manufactured with depletion mode GaAs pHEMT process.
