The NuPower Xtender ™ 12B04A-02 L-Band Bidirectional Amplifier module is a small, broadband, high-performance RF amplifier that provides 17 watts of RF output power from 1.0 to 2.0 GHz.

The bidirectional amplifier is ideal for extending the communication range of half-duplex transceivers with constant-envelope waveforms (i.e. PSK- and FSK-based modulations, such as SOQPSK and GFSK), and generates 17 Watts of RF transmit power. In receive mode, the NuPower Xtender offers a low noise figure of 3.5 dB and a low noise amplifier that provides 13 dB of gain. The module accepts a +5 dBm input level and provides a minimum of 37 dB of transmit gain, all while operating with 30% or better power efficiency at most frequencies.

The NuPower Xtender features the option of manual transmit / receive (T/R) mode selection or automatic transmit sensing, coupled with an extremely fast T/R mode switch time of

With a small form factor (6.9 cubic inches) and state-of-the-art Gallium Nitride (GaN) power amplifier device technology, the NuPower Xtender 12B04A-02 is ideal for broadband RF telemetry and communication systems that require reliability and minimal size, weight, and power consumption (SWaP).
