High-Power Tunable Filter
CB503
-
The need for tunable filter technology originates from the fact that high power communication systems and IED Jammer transmitters severely limit the use of tactical radio communication systems on the battlefield.This clash within the radio’s spectrum during tactical missions is often de-conflicted using fixed high Q, high power RF bandpass and bandstop filters installed prior to mission. This can limit operational effectiveness due to the potentially large number of fixed filters required within the allocated radio communication channels, which need be transported, stored in the field, and fitted by trained personnel. Many of these fixed filters centred within the octave wide tuning range could be replaced by a single high-Q tunable filter.

Wide Band Filters (multi-octave)
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.

RF Filters
-
RF Filters block unwanted frequencies when testing electronic devices for emissions during EMC testing. They attenuate unwanted frequencies and allow the desired signals through. The RF filters isolate the device under test from external RF noise, this increases the reliability and accuracy of the EMC testing by preventing out-of-band noise and harmonics.
