www.DataSheet4U.com HMC-C018 0.5dB LSB GaAs MMIC 6-BIT DIGITAL SERIAL CONTROL ATTENUATOR MODULE, DC - 13 GHz v00.0306 9 ATTENUATORS - CONNECTORIZED MODULES Features 0.5 dB LSB Steps to 31.5 dB CMOS Compatible Serial Data Interface ± 0.3 dB Typical Bit Error Hermetically Sealed Module Typical Applications The HMC-C018 is ideal for: Telecom Infrastructure Military Radio, Radar & ECM Space Systems Test Instrumentation Field Replaceable SMA Connectors -55 to +85 C Operating Temperature General Description The HMC-C018 is a DC to 13 GHz 6-bit GaAs IC Digital Serial Control Attenuator housed in a miniature hermetic module. This wideband attenuator features 3.6 dB typical insertion loss, +38 dBm input IP3, and bit values of 0.5 (LSB), 1, 2, 4, 8, and 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is excellent with ±0.3 dB typical step error. A six bit CMOS compatible serial control word is used to select each attenuation state and a single VDC bias of -5V allows operation at frequencies down to DC. Removable SMA connectors can be detached to allow direct connection of the module’s I/O pins to a microstrip or coplanar circuit.
