The compact RF power amplifier designed by Empower RF Systems comes in three models, covering frequency ranges of 20 to 500 MHz, 500 to 1000 MHz and 20 to 1000 MHz.

Using high-power LDMOS technology, the amplifier is significantly smaller than competing products yet is able to deliver a wide frequency response, high gain, high peak power capability and low distortion, claims the manufacturer.

Gain is specified as a minimum of 60 dB at the 1 dB gain compression point, maximum input return loss is -10dB, typical noise figure is 10 dB, and typical IP3 is given as +69 dBm. The amplifier's specifications are guaranteed across the full bandwidth and the full operating temperature range of -10 to 50ºC.

In addition to a touch-screen interface for local control, the PA incorporates Ethernet, RS232 and USB communication interfaces as well as an embedded web server for remote management and diagnostics. Using a web browser and the unit's IP address allows ease of access with the benefit of multilevel security.

The amplifier also features built-in protection circuitry that continuously monitors critical parameters and automatically takes any necessary action to avoid damage to the unit.
