The NuPower Xtender ™ 12C04A Bidirectional L- & S-Band Amplifier module is a small, broadband, high-performance RF amplifier that provides 15 watts of RF power across the L- and S-band frequencies of 1.0 to 2.5 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 15 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 12C04A bidirectional amplifier module is ideal for broadband RF telemetry and communication systems that require reliability and minimal size, weight, and power consumption (SWaP).
