“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. Fairview’s new selection of high power coaxial limiters are now in- stock and available to ship today.

option in combination with the 120 MHz real-time bandwidth ensures reliable detection of fast bursts and frequency-agile signals. Even the most advanced hoppers with extremely high hop rates are detected under demanding SNR environments. The Hopper Detector plugin provides real-time information about detected hoppers containing bandwidth, dwell time and time-of-arrival information. Using the 32768-point FFT, the real- time frequency resolution is less than 5 kHz over the full 120 MHz bandwidth. The transformation is processed in a high-performance FPGA. The continuous detection without any gaps makes the R4000 a very powerful real-time signal analyzer. In parallel to the PSD (Power Spectral Density), IQ content of sub- bands or even the full bandwidth can be retrieved and forwarded to the sensor controller. This allows to detect and analyze thousands of signals in parallel. Utilizing the 4096-point FFT option, the time resolution of the spectrum can be as fast as 25.6 µs per spectrum. This is orders of magnitude faster than swept analysis techniques and meets the demand for systems being able to capture today’s hopping, transient signals.

Fairview Microwave Releases New Coaxial High Power RF, Microwave and Millimeter Wave Limiters RF Limiters with High CW Power Handling Up to 200 Watts Peak Power New from Fairview Microwave Allen, TX – Fairview Microwave Inc., a supplier of on-demand microwave and RF components, introduces a new family of broadband, high power limiters that aid in protecting sensitive RF receivers and components such as LNAs that are in close proximity to high power signals. The new high power limiters from Fairview Microwave operate over broad frequencies ranging from 0.5 GHz to 40 GHz depending on the model. This release contains seven limiter designs featuring limiting thresholds between 3 to 10 dBm and low leakage power of 10 to 15 dBm. Fairview’s new selection of coaxial limiters exhibits high CW power handling up to 200 Watts peak power and fast recovery times of 10 to 100 nanoseconds Fairview Microwave’s new high power, broadband limiters are constructed with high-rel, ruggedized packages that are designed to meet MIL-STD-202 environmental conditions for humidity, shock, vibration, altitude and temperature cycle. These 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.
