HMC-C018
Features
0.5 d B LSB Steps to 31.5 d B CMOS patible Serial Data Interface Typical Bit Error: ±0.3 d B Hermetically Sealed Module Field Replaceable SMA Connectors -55 °C to +85 °C Operating Temperature
General Description
The HMC-C018 is a DC to 13 GHz 6-bit Ga As IC Digital Serial Control Attenuator housed in a miniature hermetic module. This wideband attenuator features
3.6 d B typical insertion loss, +38 d Bm input IP3, and bit values of 0.5 (LSB), 1, 2, 4, 8, and 16 d B for a total attenuation of 31.5 d B. Attenuation accuracy is excellent with ±0.3 d B typical step error. A six bit CMOS patible 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.
Electrical Specifications, TA = +25 °C, with Vdc = -5V and 0/+5V CMOS Control
