HMC110G16 v01.0301 MICROWAVE CORPORATION 1 dB LSB GaAs MMIC SMT 5-BIT DIGITAL ATTENUATOR, DC - 2.0 GHz ATTENUATORS - SMT 2 Typical Applications Features • Base station Infrustructure Bandwidth: DC - 2 GHz • Portable Wireless Low Insertion Loss: 5 dB • CATV & DBS 31dB Attenuation Range • Military, Space & Test Equipment Fast Switching: 6 nS Functional Diagram General Description 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 -5V 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.
