Product Description

The BW AM 1A is a professional 1 kW solid-state AM transmitter designed for medium-wave broadcasters who need exceptional audio quality, efficiency, and reliability. Built with advanced Class E MOSFET RF amplification and PWM digital modulation, it delivers excellent spectral purity and low-distortion audio across the full 522 kHz – 1705 kHz band.

Using proven Broadcast Electronics engineering, the BW AM 1A transmitter features a modular solid-state design for easy servicing and long-term stability. Its compact rack-mount form factor and robust power supply make it ideal for both main-service and backup medium-wave transmission sites. The transmitter provides built-in diagnostics, automatic fault recovery, and intelligent protection circuits against over-temperature, high SWR, over-voltage, and over-current conditions.

Integrated remote monitoring and control via SNMP and web interface allow engineers to manage performance, modulation levels, and fault status from anywhere. The transmitter’s high AC-to-RF efficiency reduces operating costs while maintaining precise frequency stability and outstanding reliability.

The BW AM 1A also supports optional C-QUAM AM Stereo operation, offering clear stereo separation and enhanced audio fidelity for modern medium-wave broadcasting. It meets or exceeds FCC and CCIR technical standards for spectral purity and harmonic suppression, ensuring a clean, interference-free signal.

With its combination of modern DSP audio processing, rugged construction, and smart cooling design, the BW AM 1A provides broadcasters with consistent, professional performance and the confidence that their signal will stay on-air in every condition. This AM transmitter for broadcasters represents the ideal balance between performance, reliability, and total cost of ownership for today’s radio operations.
