HMC110G16 MICROWAVE CORPORATION GaAs MMIC SMT 5 - BIT DIGITAL ATTENUATOR DC - 2.0 GHz FEBRUARY 2001 V01.0301 Features General Description BANDWIDTH: DC-2 GHz The HMC110G16 is a 5-bit surface mount hermetically sealed digital attenuator. Each bit is activated by applying a 0V control, and then disabled by applying -5 V control to the specified control pin. The five primary attenuation states can be activated independently, or collectively for a maximum combined attenuation level of 31 dB. See the non-hermetic wide band DC - 6 GHz HMC110C14.
