RF power doubler

26 June 2019 Telecoms, Datacoms, Wireless, IoT

The QPA3357 from Qorvo is a power doubler that operates from 47 to 1218 MHz. It provides an output power of 57 dBm, a gain of 28 dB, and has a noise figure of 4,5 dB. This power doubler is matched to 75 Ω, requires 24 V of power supply, and consumes 10,8 W of power.

The device is manufactured using a GaAs pHEMT/MESFET process and is available in an SOT-115J package. The doubler can be used in CATV amplifier systems and for DOCSIS 3.1 applications.
