Armstrong FM5000B

Armstrong Solid State FM transmitters utilize a building block approach to achieve the required transmitter output power. Multiples of either their 650 Watt, 1.3 kW or 2.5 kW self-contained Solid State Amplifier are rack mounted with an appropriately sized driver and externally combined. This model FM5000B is a 5 kW transmitter.

These amplifiers use RF modules that contain the Philips BLF 278 MOSFET. This commonly available FET has been proven in thousands of solid state transmitters in use worldwide.

Armstrong ensures that each output device is thermostatically protected and protected against excessive VSWR by a fold-back circuit, which proportionally reduces power when VSWR is present. In addition the transmitter combiner also triggers fold back when external VSWR is detected.

Metering and Alarm indications are available for each amplifier, the exciter and the driver. Plus, overall transmitter metering and alarms are available both on the transmitter and for remote monitoring via DB25 connector located on the rear panel of their chassis.

The transmitters also come with a CD-quality Exciter, redundant power supplies, are remote control ready, and are compatible with HD Radio.

This series is available in models from 650 watts to 12.5 kW. Call for BSW's low prices.

Note: Photo and Literature Link below features the FM10000B 10 kW transmitter to represent the series.

Armstrong transmitters are also available without FM Exciter at reduced cost. Call us for more details.
