Broadcast Electronics AM 1A – 1 kW Solid-State AM Transmitter

Trusted Efficiency and Broadcast Reliability

Broadcast Electronics AM 1A – 1 kW Solid-State AM Transmitter delivers proven reliability and excellent efficiency for continuous AM broadcast operation. Compact, rugged, and fully solid-state, it provides 1 kW of clean RF power with outstanding linearity and low distortion – ideal for both main and backup transmission sites.

Using rugged MOSFET amplification and a modular power-supply design, the AM 1A achieves better than 80 % AC-to-RF efficiency. This reduces operating costs and heat output while ensuring dependable long-term performance with minimal maintenance.

Superior Audio Quality

A DSP-based modulator ensures precise carrier and sideband performance, providing low-distortion sound that meets or exceeds international AM spectral standards. Broadcasters benefit from consistent modulation accuracy and clean, balanced audio across the entire AM band.

Smart Control and Remote Monitoring

Local and remote control options include TCP/IP, SNMP, and RS-232. The intuitive front-panel LCD interface displays forward power, modulation, PA current, and alarms in real time – allowing engineers to manage the system confidently from anywhere.

Built for 24/7 Operation

Integrated protection for VSWR, over-temperature, and power overload combined with temperature-regulated cooling and field-replaceable modules ensures maximum uptime even under demanding conditions.
