HMC-C053 v01.0608 VOLTAGE VARIABLE ATTENUATOR MODULE, DC - 20 GHz Features 2 Wide Bandwidth: DC - 20 GHz Low Phase Shift vs. Attenuation ATTENUATORS 30 dB Attenuation Range Up to 12 GHz Hermetically Sealed Module Field Replaceable SMA Connectors Typical Applications -55 to +85 C Operating Temperature The HMC-C053 is ideal for: • Telecom Infrastructure • Military Radio, Radar & ECM • Space Systems General Description • Test Instrumentation The HMC-C053 is an absorptive Voltage Variable Attenuator (VVA) operating from DC - 20 GHz. The HMC-C053 features a simple single voltage attenuation control, 0 to -3V. The device is ideal in designs where an analog DC control signal must control RF signal levels over a 30 dB amplitude range. Its broad frequency range makes it an attractive choice for many applications particularly those involved with AGC or temperature compensation of multiple gain stages, typically found in microwave radio or test instrumentation architecture. Removable SMA connectors can be detached to allow direct connection of the module’s I/O pins to a microstrip or coplanar circuit.
