ERF-5W™ Series (Single & Dual)



Product SKU ID: 

Product Name : ERF-5W™ Series (Single & Dual)

The new ERF-5W™ filter takes Pole/Zero’s MINI-ERF® technology to a higher level of RF power handling, with 5W (average) in-band power handling, and covering the entire military tactical radio tuning range of 30-520 MHz in one integrated package. This tunability is accomplished by the use of three poles of selectivity, multiple internal tunable filters along with high performance PIN diode RF band select switches. The tunable filters are designed to minimize size and power consumption, while maintaining high RF power handling and linearity characteristics. Serial control is accomplished via a standard Serial Peripheral Interface (SPI)-based bus.








The reduced size, weight, power consumption, and cost of Pole/Zero’s Integrated Microwave Notch Filters (IMF Filters) make them suitable for applications in the Electronic Warfare and SATCOM markets.
