Export Classification


The NuPower XtenderTM 12B04A-D27 is a small, lightweight, and power-efficient bidirectional amplifier ideal for extending the communication range of half-duplex S-band transceivers running constant-envelope or near-constant-envelope waveforms. The bidirectional amplifier generates 20 Watts CW (typ) of RF power from 1000 to 2500 MHz in transmit mode and the integrated low-noise amplifier provides a minimum of 14 dB (typ) of gain in receive mode.

Based on the latest gallium nitride (GaN) technology, the Xtender offers 30% power efficiency (typical) within a small form factor making it ideal for integration into space-constrained platforms. Accepting a +27 dBm RF input, the Xtender provides more than 15 dB of transmit gain. The Xtender also features over-voltage and reverse-voltage protection and operates over a wide temperature range of -30 to +60 °C.
