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

Key Features: Power Up to 1 Watt Instantly boost low-power transmitters to a full 1W for long-range, reliable coverage. 12-14 dB Gain Clean, stable amplification with excellent gain flatness. Ultra-Selective Band-Pass Filtering Custom-tuned output filter for maximum signal purity and harmonic suppression. Wide Frequency Options Available in multiple UHF bands from 470 MHz to 960 MHz. Adjustable Gain in 0.5 dB Steps Fine-tune performance on the fly with an intuitive OLED display. Built-In DC Voltmeter Real-time voltage monitoring for peace of mind during critical events. Lockable Settings Prevent accidental changes with the secure Lock Menu. Compatible with Any UHF Transmitter Works with Hybrid FM and Analog FM across a wide input range (0 dBm to 18 dBm). Rugged CNC-Machined Housing Durable, black-anodized aluminium body designed for harsh environments. Cool & Compact Integrated heat-sink design and advanced PCB thermal optimisation for dependable performance.   The UHF AWPB-1W amplifier delivers up to 1W output power, excellent gain flatness, wide dynamic range, and a low Noise Figure. It is designed to boost low-power radio microphone transmitters to a full 1W for applications such as sports audio links, car-to-car recording, IEM TX range extension, and similar long-range needs. A custom-tuned, highly selective band-pass filter in the output stage sets the operating frequency range and effectively suppresses 2nd and 3rd harmonics. Available Frequency Bands: 470–700 MHz 470–865 MHz 500–865 MHz 500–960 MHz Gain can be adjusted in 0.5 dB steps via the intuitive OLED interface. A real-time DC voltmeter monitors input voltage continuously, and the Lock Menu prevents unintended changes to user settings. The booster is compatible with any UHF wireless transmitter operating within the same tuning range, including Digital, Hybrid FM and Analog FM systems. Its wide input dynamic range accepts transmitter power levels from 0 dBm (1 mW) up to 18 dBm (63 mW).The AWPB-1W features a compact, custom-designed enclosure with an integrated heat sink and advanced PCB thermal design to minimize heat build-up. The CNC-machined aluminium housing is black-anodized and laser-marked, providing durability and reliable performance in demanding environments.   Technical Specification Maximum RF Output Power 1Watt ( 30dBm) Gain 12-14 /-1.0dB user adjustable in 0.5dB steps ( 13dB nom.)
