NUPOWER XTENDER VU4GX01 OVERVIEW
The NuPower Xtender™ VU4GX01 Bidirectional VHF/UHF Amplifier module is a small, lightweight, and
power-efficient bidirectional amplifier (BDA) ideal for extending the communication range of half-duplex
transceivers running high peak-to-average waveforms such as OFDM or LTE. The bidirectional amplifier
generates 4 watts of linear RF transmit power (-33 dBc ACPR) from 225 to 512 MHz in transmit mode
and the integrated low-noise amplifier provides 15 dB of gain in receive mode.
Based on the latest Gallium Nitride (GaN) technology, NuPower’s high-efficiency and 3.8 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.
