BTECH AMP-U25 Amplifier for UHF (400-480MHz), 20-40W Output (2-6W Input), Analog and Digital Modes, Compatible with All Handheld Radios: BTECH, BaoFeng, Kenwood, Yaesu, ICOM, Motorola

From the manufacturer

AMP-U25 Amplifier

Easily amplify your handheld radio to 20-40W (2-6W Input). The AMP‑U25 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‑U25 will also work with any handheld radio that outputs 2W–6W with the appropriate connecting RF cable. The AMP‑U25 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‑U25 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-U25 includes voltage spike suppression, over-temperature protection, RF sensing, and automatic power control (APC) to protect it under adverse operating conditions.

AMP‑U25 - UHF 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 Controlled Connect 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 Controlled Connect 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 Controlled Connect 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.

Product Quick Look

Technical Details: • Frequency range: ◦ AMP-U25 : 400 – 480 MHz • Power supply: 13.8 VDC (±15%), 5.5 A maximum • Input RF power: 2 - 6W (±10%) • Output RF power: 20 - 40W • Size: 5.5-in D x 4.5-in. W x 1.4-in. H (40 mm D x 115 mm W x 36 mm H) • Net weight: 1.8 lbs. (800 g) The BTECH AMP-25 Series is designed to work with any BaoFeng or BTECH handheld transceivers, but it will also work with any handheld radio that outputs 2 W – 6 W with the appropriate cable. With the included Radio to Amplifier RF Cable, the amplifier will also work with Wouxun transceivers, some TYT transceivers, and some Kenwood transceivers. If the supplied cables do not connect to your radio, you will need to use adaptors or build cables with the appropriate connectors. Your BTECH AMP-25 amplifier does not include an antenna. It is very important to not transmit without an antenna or dummy load connected to the ANT connector on the rear panel of the amplifier. Transmitting without an antenna or dummy load may cause harm to the radio equipment. When choosing an antenna, make sure that it is suitable for the bands you plan on transmitting and receiving on. For example, if you plan on transmitting on 145MHz, make sure that the antenna you select has an SWR of 1.5:1 or less on that frequency. Using an antenna with an SWR greater than 1.5:1 could damage the amplifier. If you plan to use a magnetically-mounted (mag-mount) antennas, ensure that the antenna is grounded to a metal surface, such as a vehicle body. Magnetically-mounted antennas do not operate properly without a good ground.
Easily extend the communication range of your handheld radio; Use the AMP‑U25 to create: a mobile radio with a vehicle mounted antenna, a high power field radio with a field deployed antenna, a home/base radio attached to a mast. Your handheld radio connects in seconds and can just as easily disconnect and be taken on the go.
Kit Includes the necessary cables and interface connectors to easily connect to BTECH and BaoFeng Radios.
Recommended Accessory: Pair with the BTECH UT-72 Antenna or NMO-72 Antenna & compatible mount for an easy mobile or field deployed solution.
