Crane Aerospace & Electronics Microwave Solutions STL 301 PIN-SCHOTTKY LIMITER TECHNICAL FEATURE FEATURES 1 Watt CW Capability Wide bandwidth: 0.5 to 18 GHz Low VSWR < 2.2:1 Internal DC Blocks DESCRIPTION TYPICAL TRANSFER CURVE The STL 301 Limiter is a passive, broadband integrated assembly designed for receiver protection and power leveling applications. This is a PIN-Schottky design with built-in DC blocking capacitors. Metallurigical bonds are used to provide the reliability required by the most severe environments. Systems applications include protection of transistor and FET amplifiers, mixers and detectors in ECM, telecommunications and radar systems.
