Designed to protect sensitive RF receivers and components such as LNAs in close proximity to high power signals, a new family of broadband high-power limiters by Fairview Microwave hit the shelves.
The limiters operate over broad frequencies from 0.5 GHz to 40 GHz depending on the model. This release contains seven limiter designs featuring limiting thresholds between 3 dBm to 10 dBm and low leakage power of 10 dBm to 15 dBm. The new family exhibits high CW power handling up to 200 Watts peak power and fast recovery times of 10 to 100 nanoseconds.
The new limiters are constructed with high-reliability and ruggedized packages designed to meet MIL-STD-202 environmental conditions for humidity, shock, vibration, altitude and temperature cycle. The components are also guaranteed to operate over temperature ranges from -54° C to 85° C. The 50-Ohm hybrid designs also use limiting diode circuitry and eliminate the need for external matching components.
“Our new portfolio of high power RF limiters provides designers and engineers the components needed to protect their sensitive RF receiver components from high power signals that could result in irreparable damage to the system,” says Brian McCutcheon, vice president and general manager at Fairview Microwave. “These high power limiters offer industry-leading performance and are well suited for applications such as electronic warfare, instrumentation, fiber optic communication systems, radar, SATCOM, point-to-point radio, telecom and R&D.
