From the manufacturer
AMP-U25D Amplifier
Easily amplify your handheld radio to 20-40W (2-6W Input). The AMP‑U25D is a time-saving (and cost saving) alternative to mobile and base radios that simply duplicate the same programming your handheld radio already has.
Supported Radios
The AMP‑U25D will also work with any handheld radio that outputs 2W–6W with the appropriate connecting RF cable. The AMP‑U25D includes the SMA Female connecting cable to hook right up to BTECH and BaoFeng radios right out of the box.
Lightweight Amplifier
Easily install in a home or mobile environment; the AMP‑U25D measures just 5.5" x 4.5" x 1.4" and weighs just 1.8lb making it the perfect companion for field operation without adding a lot of weight.
Cleaner Output Signal
Harmonic filters on the input allow the amplifier to transmit a cleaner output signal. The amplifier is so well engineered that in most circumstances it transmits a cleaner, purer signal then it receives from your handheld radio.
Protection Circuitry
The AMP-U25D includes voltage spike suppression, over-temperature protection, RF sensing, and automatic power control (APC) to protect it under adverse operating conditions.
AMP‑U25D - UHF (+DMR) Amplifier
What is it?
The BTECH AMP-U25 amplifier is a portable, lightweight, wide coverage RF power amplifier for handheld radio equipment and is equally capable of amplifying both analog and digital signals.
Pair with the UT-72 Antenna for easy installation to your vehicle, or connect to another UHF base, mobile, or field antenna.
Supported Amplification Modes
The AMP-U25 operates from 400-480 MHz and can be used for analog FM, P25 Phase 1, C4FM (System Fusion), NXDN, IDAS, dPMR, and MPT1327 modes.
The AMP‑U25 supports out-of-band transmitting, while the amplifier is turned off. When transmitting out-of-band the amplifier will pass-through the signal without amplification.
Built In Loud-Speaker
When you connect your handheld radio with the radio control cable; the amplifier will use it's own loud 4W built-in speaker to broadcast the incoming audio.

Three Primary Modes of Amplification
|
|
|
|
|---|---|---|
Radio ControlledConnect to the antenna output of the handheld transceiver to the RF-IN connector on the rear panel of the amplifier with the Radio to Amplifier RF cable. Transmit and receive right on the Handheld radio - while your output signal is amplified. |
Accessory ControlledConnect a speaker microphone, headset, or compatible accessory to the radio. Transmit and receive right on the accessory connected to the Handheld radio - while your output signal is amplified. |
Amplifier ControlledConnect the speaker microphone to the MIC jack on the front panel of the amplifier. Connect to the antenna output of the handheld transceiver to the RF IN connector on the rear panel of the amplifier with the Radio toAmplifier RF cable. Connect the accessory port of your radio to the Control jack on the front panel of the amplifier using the Amplifier Control Cable. Transmit and receive using the speaker microphone on the amplifier while incoming audio is relayed through the loud amplifier speaker. |
