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. The lter bank is powered by +5V DC applied to an external bias pin mounted on the side of the unit. A grounding terminal is also provided. One control pin provides TTL selection of the desired operating channel. The unit is bi-directional with SMA eld removable connectors. All speci cations above measured at 25 oC Dimensions and Connections 3.50” L x 1.10” W x 0.45” H excluding SMA connectors and control pins. The chassis is machined aluminum with a silver plate nish. Control pins are .030” dia.
