Labtech Launches New Range Of DLVAs

San Francisco -- IEEE MTT-S International Microwave Symposium -- Labtech Microwave launched a new range of Detector Log Video Amplifiers (DLVAs).

To meet the growing high tech global demands and the ever-increasing 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, the DLVAs 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 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 2 GHz to 18 GHz. 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 2 GHz to 18 GHz. 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 - 41mm x 31mm x 12mm for the LMV005 and 50mm x 45mm x 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.
