TESEQ CBA 3G-025 Class A Broadband Amplifier 800 MHz – 3.1 GHz 25 W

Description

Designed specifically for Radiated EMC testing, this mismatch tolerant Class A amplifier delivers power continuously into the poor and variable match typically associated with testing above 1 GHz. Although antennas are usually well matched at these high frequencies, the presence of the EUT in the path of the antenna causes high levels of reflected power which only full Class A amplifiers can tolerate.

Whilst antenna gain is relatively constant, increasing cable losses at the higher frequencies demand increasing power with increasing frequency. Teseq amplifiers are therefore designed to maintain their high linear output power right up to and beyond the defined frequency range.

The GaAs Class A design ensures a high reliability, low distortion linear performance across the frequency range. This design also ensures that the amplifier will continue to operate at full power even when presented with an open or short circuit at its output.

Features

  • Class A linear and low distortion design
  • High reliability gallium arsenide technology
  • Mismatch tolerant and unconditionally stable
  • Wide instantaneous bandwidth
  • Three year parts and labor warranty
