GENERAL DESCRIPTION
The HMC-C053 is an absorptive voltage variable attenuator
(VVA) operating from dc to 20 GHz. The HMC-C053 features
a simple single voltage attenuation control, 0 V to −3 V. The
device is ideal in designs where an analog dc control signal
must control radio frequency (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 automatic gain control (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 input/output pins to a microstrip
or coplanar circuit.

overall gain for temperature or frequency. This is only one of
the many applications of the HMC-C053.
In Figure 14, the HMC-C053 is used to make a variable gain
amplifier. In this application circuit, the HMC-C053 varies
