Teseq CBA 3G-450 Broadband Amplifier 800 MHz – 3.1 GHz 450W
Description
Teseq CBA 3G-450 Broadband Amplifier 800 MHz – 3.1 GHz 450W is 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 fully Class A amplifiers can handle.
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.
Features
- Class A linear and low distortion design
- High reliability gallium arsenide technology
- Mismatch tolerant and unconditionally stable
- Wide instantaneous bandwidth
