• EW, ELINT & IFM Receivers
• DF Radar Systems
General Description
• ECM Systems
The HMC-C078 is a Successive Detection Log Video
Amplifier (SDLVA) which operates from 2 to 20 GHz.
The HMC-C078 provides a logging range of 50 dB.
SDLVAs
• Broadband Test & Measurement
• Power Measurement & Control Circuits
• Military & Space Applications
This product comes standard with two female SMA
field replaceable connectors but can also be used with
blind mate SMP connectors or as a drop-in module.
The package size measures 1.5 x 1.32 x 0.23” (38.10
x 33.53 x 5.84 mm) making it ideal for environmentally
robust applications where space is limited. In addition
to the video output signal, the HMC-C078 has a limited
RF output port.
Functional Diagram
The HMC-C078 has integrated voltage regulators on
both the positive and negative supply.
