Audio Wireless Transmitter Power Booster Module (AWPB-1W)

The AWPB-1W amplifier offers up to 1W of output power and a 12dB small signal gain, with excellent gain flatness along with outstanding dynamic range and noise figure. Designed to boost low-power radio microphone transmitter outputs up to 1Watt. Applications such as audio links in sports events, during filming for car-to-car recordings, boosting IEM transmitters to cover larger areas and more.

The booster power amplifier output stage employs a very selective custom-tuned band-pass filter which determines the operating frequency range and suppresses the 2nd and 3rd harmonics of the transmitter.

The booster gain is user adjustable in 0.5dB steps to suit different applications, through the intuitive OLED display, a real-time dc voltmeter continuously monitors input dc volts. The Lock Menu enables Lock the user adjustable setting against accidental change in action.

Compatible with any UHF wireless transmitters operating in the same tuning range, Hybrid FM and Analogue FM. Not suitable with Digital radio mic transmitters. A very wide dynamic input range accepts transmitter power levels from 0dBm (1mW) to +25dBm (316mW).

The AWPB-1W enclosure is a custom design for compactness as well as an integral heat sink minimizing the unit’s heat dissipation, using advanced PCB designs technique the heat dissipation is minimized. Overall, the box design is to withstand the heavy-duty use of the harsh environment, providing long life and consistent performance under difficult operating conditions. The booster box is a custom design CNC machined aluminum, black anodized finish with laser marking.
