0.1 GHz to 40 GHz, 31 dB, 5-Bit Digital Attenuator HMC-C584 Preliminary Technical Data FEATURES GENERAL DESCRIPTION 1.0 dB LSB steps to 31 dB Single positive control line per bit ±1.0 dB typical bit error Input IP3: 43 dBm CMOS-compatible control Hermetically sealed module Field replaceable K-type connectors Operating temperature: −55°C to +85°C The HMC-C584 is a 0.1 GHz to 40 GHz, 5-bit, gallium arsenide (GaAs) IC digital attenuator housed in a miniature hermetic module. This wideband attenuator features 7 dB typical insertion loss, 43 dBm input IP3, and bit values of 1 dB (LSB), 2 dB, 4 dB, 8 dB, and 16 dB for a total attenuation range of 31 dB. The attenuation accuracy of the device has a ±1.0 dB typical step error. Five control voltage inputs, toggled between 0 V and 5 V, are used to select each attenuation state. Removable K-type connectors can be detached to allow direct connection of the input/output pins of the module to a microstrip or coplanar circuit.
