Fast frequency switching time – YIG filter switching speed of ≤ 75 µs/GHz
Expanded operational frequency range – ability to operate over all X-band radar frequencies
Precise center frequency accuracy and stability – settled to within ≈ 1 MHz of commanded frequency within the switching speed time
Rugged and reliable system – must operate in some of the worst environmental areas of aircraft – high vibration and noise environments
Self cooling – ability to operate using convection and radiation cooling (no heat sinking to aircraft)
Special case – multiple filter channels requiring channel gain
Tight control of gain and gain tracking of multiple channels of filtering – on the order of 1 dB RMS over temp. over full ECM band
Giga-tronics has the industry’s most advanced line of tunable, synthesized Band Reject Filters (BRF) for ESM and EW applications. These high-speed, tunable notch filters can quickly block interference from CW and narrow-band emissions. Using proprietary driver and PLL technology, these filters offer tuning speeds that are 10x faster than open loop YIG filters designs.
