Small, rugged DLVAs suit airborne apps

Labtech Microwave has launched a new range of detector log video amplifiers (DLVAs).

To meet the growing high tech global demands and the increasingly complex subsystem designs, the company is introducing a new miniature Extended Range DLVA (ERDLVA) with an 80dB dynamic range to complement its Standard Range DLVA product lines.

With DC-coupled and CW-immune options available, Labtech said the new devices have a temperature range of -40°C to 85°C, are small in size and weight for airborne applications, have fast rise times, and all units are hermetically sealed.

All manufacturing and environmental testing is performed in a class 10,000 clean room with fully automated chip placement and wire bonding. Labtech said it can fully test components/sub-systems and integrated assemblies to the full Mil-Std requirements demanded by various customers around the world.

The LMV005 is a CW-immune DLVA with a 45dB (-40dBm to 5dBm) dynamic range operating over the frequency range from 2GHz to 18GHz. Chip hybrid circuits are used throughout to minimize size and maximize performance.

The frequency flatness of ±1dB at the video output is maintained over the full dynamic range and temperature range of -40°C to 85°C, as is the 25ns video pulse rise time. Custom options for DC or AC coupling and dynamic range to 50dB are available.

The LMV001 is a CW-immune ERDLVA with an 80dB (-70dBm to 10dBm) dynamic range operating over the frequency range from 2GHz to 18GHz. In addition, the unit includes an output RF port that delivers 40dB gain over the full frequency range.

The frequency flatness of ±2dB at both the video and RF outputs is maintained over the full dynamic range and temperature range of -40°C to 85°C as is the 25ns video pulse rise time.

The small outline—41-by-31-by-12mm for the LMV005 and 50-by-45-by-12mm for the LMV001—and rugged hybrid construction makes both products suited for the restricted space and weight environments of modern airborne and manpack applications.
