New Coaxial, High Power Limiters Help Protect Sensitive RF Receivers and Components
Fairview Microwave releases new RF, microwave, and millimeter wave limiters
This release contains seven limiter designs, with limiting thresholds between 3 to 10 dBm, and low leakage power of 10 to 15 dBm. Fairview’s new selection of coaxial limiters reportedly exhibits high CW power handling up to 200 Watts peak power, and fast recovery times of 10 to 100 nanoseconds.
Fairview Microwave’s high power, broadband limiters are constructed with high-reliability, ruggedized packages that are 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 utilize limiting diode circuitry and do not require any external matching components, according to Fairview.
“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,” said Brian McCutcheon, vice president and general manager at Fairview Microwave, in a statement. “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.”
