  • 3 Watt UHF Amplifier
  • Instantaneous Bandwidth
  • Rugged Compact Design
  • Operates into any Load
  • Low Distortion

The 403LA Broadband Amplifier is a rugged source of RF power suitable for a variety of UHF signal distribution and general laboratory applications. It is a compact fully solid state design. It features low-level intermodulation distortion and inherent protection against short and open circuit loads. The 403 LA amplifies the inputs of AM, FM, SSB, pulse and other complex modulations within its output and bandwidth capability.

High Reliability
Complete stability and rugged design ensure operation into mismatch and overdrive conditions. The 403 LA will withstand a + 13dBm Input signal for all load conditions.

Flexible Operation
The 403LA produces 3 Watts of Class A linear output power over a frequency range of 150 kHz to 300 MHz with a nominal gain of 37 dB (+/-2dB). In order to provide exceptionally low levels of IMD, highly linear RF devices are used, with feedback, in the driver and output amplifier stages. All harmonics are more than 25 dB below the fundamental frequency at 2.7 Watts Pout.

Rugged Design
An integral power supply allows for operation directly from an input of 115/230 V single phase. Both the power supply and the forced air cooling are conservatively designed for operation over a wide temperature range.
