B1 — Up/Down Converter

Wideband 6 – 18 GHz to 4 GHz IF conversion

Bidirectional up/down converter between the SDR's 4 GHz IF and the 6 – 18 GHz RF band. Includes DSA, gain stages, BPF IF filter, digitally tuneable RF filter (DTF), LNA on Rx, and the Rx duplex switch. Designed for SIGINT and broadband microwave EW where tuning agility matters more than peak power.
