Pasternack expands its line of wideband high power coaxial limiter

     Pasternack, Inc., a brand of Infinite Electronics and a leading supplier of RF, microwave and millimeter wave products, has expanded its line of broadband high-power coaxial limiter products designed to better protect sensitive components in receiver circuits and other microwave circuits operating near high-power signals. Typical applications of this series of RF limiter include electronic warfare, military communications, instrumentation, optical fiber communication systems, satellite communications, radar, point-to-point wireless, telecommunications, and research and development.

     The expanded high-power RF limiter product line consists of 13 different models that not only provide low leakage power for sensitive control components in the receiver link, but also achieve good even harmonic suppression under hard limiting conditions. This series of RF limiter operates in a wide range of broadband bands from 0.2 GHz to 40 GHz, and can protect the circuit with low leakage power of 10 to 18dBm. In addition, the series has a high continuous wave power processing capacity of 200 watts at peak power and a fast recovery time of 10 to 100 nanoseconds.

     In this series, the 50 ohm product uses a highly reliable assembly process and includes a complete limiter diode circuit system without the need for any external matching components. These products come in a compact package that supports field replaceable connectors and in-line mounting holes, and can be embedded into the circuit board. In addition, these products are ruggedified products that ensure operation in the temperature range of -54 ° C to +85 ° C and are designed to meet MIL-STD-202 shock, humidity, vibration, high altitude and thermal and cold cycle environmental conditions.

     "Our broad line of broadband high-power coaxial RF limiter offers customers a full range of highly reliable products to protect sensitive components in receiving links and other microwave circuits. In addition, these limiters are off-the-shelf products shipped on the same day of order, which can meet the urgent needs of our customers, "explains Tim Galla, Product Manager for active RF Components at Pasternack.
