RFMW Ltd. announces design and sales support for Qorvo’s QPC9314. The QPC9314’s PIN-diode based switch can handle 52 W of average power with an LTE signal (8 dB PAR) and contains two LNA stages, and a 1-bit DSA to provide a high and low gain mode.
Further integration of this module is implemented with a switch driver and DC-DC converter circuit meaning the module needs only an external 5 V power supply and 3.3 V control logic for the switch and gain control mode. Spanning 2.3 to 2.7GHz, this module provides 1.2 dB noise figure in receive mode operation and 0.5 dB insertion loss in the transmit mode.
Packaged in a compact 8x8 mm surface-mount leadless package, the switch LNA module is targeted for wireless infrastructure applications and macro or pico cell base stations configured for TDD-based architectures using an isolator.
