The HVA series of broadband PIN Diode attenuators covers the waveguide bands from 18 to 110 GHz. Full waveguide band coverage is available up to 60 GHz. The attenuators are available for applications requiring variations in power levels using a control voltage. A 0 to +5 V tuning range is used to control the attenuation level.
These designs utilize a low loss finline structure with silicon or GaAs beam lead diodes for minimum insertion loss and optimum attenuation flatness. Standard attenuation values range from 30 dB up to 50 GHz to 15 dB at 100 GHz. Options for alternateattenuation values can be offered with low loss versions and isolation levels up to 40 dB.
