NUPOWER XTENDER 12B04A OVERVIEW
The NuPower Xtender™ 12B04A Bidirectional L- & S-Band Amplifier module is a small, lightweight, and
power-efficient bidirectional amplifier (BDA) ideal for extending the communication range of half-duplex
L- or S-band transceivers running constant-envelope or near-constant-envelope waveforms. The
bidirectional amplifier generates at least 7 watts of RF transmit power (10 watts typical) from 1000 to
2500 MHz in transmit mode and the integrated low-noise amplifier provides a minimum of 13 dB of gain
in receive mode.
Based on the latest Gallium Nitride (GaN) technology, NuPower’s high-efficiency and 6.9 in.
3
form factor
make it ideal for SWaP-constrained applications. In addition, NuPower’s broadband frequency coverage
supports operational flexibility.
NuPower Xtender bidirectional amplifiers are designed with ruggedized chassis for high-reliability in
harsh environments.
