详细信息

The series VCA voltage-controlled variable attenuator covers 18 to 100 GHz in seven waveguide bands. This attenuator offers an attenuation dynamic range of 25 dB up to 50 GHz, and 20 dB at 100 GHz. Series VCA is also offered in a high attenuation version, in which the attenuation dynamic range is 25 to 40 dB, depending upon the frequency. However insertion loss is slightly higher. VCA is a reflective device.
