BTECH 'D' Series Amplifiers: Mastering Advanced Digital Modes

Advanced Digital Mode Compatibility: The BTECH 'D' Series Amplifiers, designed to seamlessly support P25 Phase 2 and DMR standards. These amplifiers are tailored for the evolving landscape of digital communication, providing crystal-clear, uninterrupted transmission across diverse settings by adeptly working with the dual time slots characteristic of TDMA systems. Intelligent Circuitry for Peak Performance: Dive into the realm of advanced digital engineering with our amplifiers, which boast state-of-the-art circuits capable of managing TDMA's swift data intervals (30ms). This precision ensures optimal channel utilization, maintaining the integrity of one time slot while actively using the other, thus enhancing the efficiency and reliability of TDMA based systems like DMR.

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

    Lynn Wilcox –

    Pretty happy over all but I get some Pickett fencing not sure what’s going on.
    Don’t get it with any other radio hooked up to the mobile antenna. Don’t sure what’s going on

    Steve Shannon –

    I am very happy with my AMP V25D
    with my btech 6×2. The only problem I have is that mic’s modular plug broke away from the mic cord. I need the wiring diagram for the 6pin modular plug or the model number of
    Correct microphone. Thanks, Steve k9sks
