Two individual channels can be customized over a
wide range of frequencies, typically 1 MHz to 2000
MHz. Channels 1 and 2 are miniature Lumped
Element Bandpass Filters. This relatively small ꢀlter
bank provides excellent Passband performance
while suppressing ultimate rejections by >50 dB out
to 18 GHz.
