Introduction：
BBV 9721 is a microwave broadband amplifier produced by Schwarzbeck, Germany and authorized by EUTTEST Shenzhen for sale. It can be used for radiating RE test in the frequency range of 18-40GHz in the darkroom, with a typical gain of up to 35dB. For testing, you need to mount this amplifier directly on the back of the antenna. Adapter and mounting bracketAM 9144The
The low-noise, low-power broadband amplifier BBV9721 can be used to increase the sensitivity of field strength tests and for generalized attenuation measurements up to 28.5 GHz. The amplifier has no internal battery and is powered by option PS 9721. A battery option is also available for this antenna, see the Options section.
