Half Watt Linear Amplifier Serves Small Cell PAs

RFMW has announces design and sales support for a high linearity amplifier from Qorvo. The QPA9421 power amplifier supports small cells operating in the 2.11 to 2.17 GHz frequency range with up to 27 dBm of linear power and 30 dB of gain. ACLR is -50 dBc at +27 dBm average output power.

Drawing 420 mA from a 4.5 volt supply, the QPA9421 also supports femtocells, customer premises equipment and data cards. It can also function as a linear driver in DAS applications, booster amps and repeaters without the need for digital pre-distortion. Internally matched to 50 ohms at both input and output, it is offered in a 7x7mm, SMT package.
