MEGA-POLE® Series
MEGA-POLE™
The MEGA-POLE filter series covers the standard frequency bands within the 30 to 450 MHz range. This new filter series provides excellent selectivity while maintaining very low insertion loss. The product line also has exceptional RF power handling capability with a high third order intercept point. The MEGA-POLE filter series can be used for transmitter applications to reduce power amplifier noise, harmonics and intermodulation products, to provide bi-directional filtering directly at a transceiver’s antenna port, or other applications requiring extremely linear, high power RF bandpass filtering. It has been designed for rugged military environments per MIL-STD-810.

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.
