Abstract
The Defence Research Establishment Ottawa (DREO) has been conducting research and development activities in the field of active missile approach warning system (MAWS) to support the CF-18 MAWS requirement. A MAWS transceiver and a controller/data acquisition system (C/DAQU) were developed by DREO for use in flight trials. To avoid the long recovery time involved with hard saturation of the analog-to-digital converter in the C/DAQU, a clamping amplifier is required for the last stage in the receive chain of the transceiver. Because no off-the-shelf product was available that would meet the stringent requirements of this application, a clamping amplifier was developed, fabricated, and tested at DREO using in-house laboratory equipment. This technical note outlines the design specifications, the performance issues (dynamic range, third order intermodulation products, and saturation recovery time), and the performance results of the clamping amplifier.
