Typical Applications
The HMC121C8 is an absorptive Voltage Variable
Attenuator (VVA) in a non-hermetic surface-mount
package covering DC - 10 GHz. It features an on-
chip reference attenuator for use with an external
op-amp to provide simple single voltage attenua-
tion control, 0 to -3V. The device is ideal in designs
where an analog DC control signal must control
RF signal levels over a 25 dB amplitude range.
Applications include AGC circuits and temperature
compensation of multiple gain stages in microwave
point-to-point and VSAT radios. See HMC121G8 for
a hermetic SMT version of this device.
