NUPOWER XTENDER VU4GX02 OVERVIEW
The NuPower Xtender™ VU4GX02 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 16 watts (Psat) or 4 watts of linear RF transmit power (‐30 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.
