High Power Switch LNA for Macro Cells

Qorvo’s 2.3 - 2.7GHz QPC9314 PIN-diode based switch module can handle 52 Watts 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 modeRFMW, Ltd. announces design and sales support for Qorvo’s QPC9314. The QPC9314’s PIN-diode based switch can handle 52 Watts 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 5V power supply and 3.3V control logic for the switch and gain control mode. Spanning 2.3 – 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 8×8 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.
