Using the same core technology as BW Broadcast FM transmitters, the PA300 300-watt FM RF amplifier is exceptional value for stations who are on a budget and also demand the best performance. When paired with a BW Broadcast exciter, or other top-quality model, the unique design of the PA300 contributes unsurpassed reliability to low-power FM transmission systems.
Compact, lightweight and efficient, the PA300 has an adjustable output from 25 to 300 watts. Also available is the PA150, adjustable from 25 to 150 watts. Internal harmonic filtering keeps your RF signal clean and compliant with all applicable CE, FCC and EU regulations. Mains voltage input is via an EMI filtered IEC power connector, which feeds two fully approved and efficient switched mode power supply modules with a universal input voltage range from 85-260 Volts AC.
The graphical LCD controller eases the management of power, as well as monitoring of key system variables. The rear panel has a BNC connector for RF input and RF output is via an N-Type socket.
The PA300 is based on a modern MOSFET device that is simple, stable and efficient. High power fans draw fresh air through the transmitter’s heatsink to keep the transistor and amplifier cool.. Amplifiers are protected from damage by temperature control systems and antenna fault (VSWR) monitoring which react to faults by reducing the output power to a safe operating level, keeping you on air rather than shutting down completely.

An RS232 control and monitor system can be managed from a standard terminal program or BW Broadcast’s included Windows application.
