Product Description

BTECH AMP-U25 Amplifier

Elevate your communication capabilities with the BTECH AMP-U25 Amplifier, designed to amplify your handheld radio's power up to 40W* (*peak 30W average), enabling more robust and clearer transmissions across the UHF band. Whether you're setting up a mobile radio in your vehicle, a high-power field radio, or a home base station, the AMP-U25 is your gateway to enhanced range and reliability.

Plug & Play: Comes with all necessary cables and connectors, making it compatible with a wide range of radios without the need for additional accessories.

Loud and Clear: The integrated 4W speaker amplifies incoming audio, ensuring you never miss a transmission.

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

  • dPMR
  • MPT1327

Universal Radio Compatibility & Adaptive Amplification

The BTECH amplifier stands out for its exceptional ability to work with an extensive range of radio brands, made possible by a simple, direct connection to the SMA jack. This feature ensures that no matter the make of your handheld radio, if it's equipped with an SMA connection, it will integrate effortlessly with our amplifier. We've included connectors for both SMA male and female configurations to accommodate the majority of radios right out of the box. For radios with different connectors, the amplifier remains compatible as long as you have the appropriate RF adapters to convert to the SMA standard.

Adaptive Output Power

Our amplifier is designed to adapt its output power based on the input it receives, optimizing performance across a range of 2W to 6W inputs. At the lower end, an input of 2W is amplified to produce an output of approximately 20W. As the input power increases, so does the output, reaching its peak efficiency with a 6W input, which yields an impressive output of around 40W in the center of the band. On average, users can expect 30W output, providing a substantial boost to transmission power. It's important to note that while the amplifier can accept up to 10W of input power, amplification levels plateau after 6W, ensuring device safety and longevity without further increasing output.

Optimized Signal Clarity

At the core of our amplifier's design are sophisticated harmonic filters on the input stage, crafted to ensure the transmission of a notably cleaner and more refined output signal. This exceptional engineering prowess enables the amplifier to consistently deliver an output that is not just amplified, but also purer and of higher quality than the signal received from your handheld radio. Whether in routine communications or critical operations, the amplifier stands out by enhancing signal clarity and reducing unwanted noise, setting a new standard for audio purity in amplified transmissions.

Explore the Versatility of the BTECH Amplifier with Three Distinct Amplification Modes

Radio-Controlled Mode

For direct and straightforward use, connect your handheld radio directly to the AMP. Simply link the antenna output of your radio to the amplifier's RF-IN connector using the provided Radio to Amplifier RF cable. This setup allows you to continue using your handheld radio as usual, but with the added advantage of amplified output signals. It's the ideal choice for users seeking amplified performance without changing their existing radio operation habits.

Accessory-Controlled Mode

Enhance your radio's functionality with external accessories. In this mode, you can connect a speaker microphone, headset, or any compatible accessory directly to your handheld radio. The amplifier still boosts your signal, but control is through the connected accessory, offering a hands-free communication experience. This mode is perfect for users who require amplified communication while needing to keep their hands free for other tasks.

Amplifier-Controlled Mode

For a fully integrated experience, use your amplifier as the central control hub. Connect your handheld radio to the amplifier as in Radio-Controlled Mode, then link a speaker microphone to the amplifier's MIC jack. Additionally, connect the accessory port of your radio to the amplifier's Control jack using the Amplifier Control Cable. This setup allows you to manage transmissions through the amplifier, utilizing its built-in speaker for louder, clearer incoming audio. This mode is best suited for stationary setups where the amplifier's features can be fully utilized.

BTECH Amplifier FAQs

Q: How do I select the right antenna to use with my amplifier?

A: Choose an antenna compatible with your transmission frequencies and ensure it has an SWR of 1.5:1 or less to prevent amplifier damage.

Q: Can any radio work with the BTECH AMP?

A: Yes, if they operate on the supported frequency of the amplifier and have 2-10W output with the correct RF cable.

Q: Can I use the amplifier in my house

A: Yes, although you would need an appropriate AC to DC power convertor such as the BTECH RPS-30M

    The amp itself is good. The quality of the antenna cable and the rj11 crimp is awful. I’ll redo the mic cable myself and I’ll definitely need to buy a better antenna cable.

    I have every one of these models and using them to boost my HTs as a base station with external antennas. The included microphone and build-in speaker are outstanding quality as compared to some Motorola products.
