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