ADL5961 Overview
The ADL5961 is a wideband, small form factor, vector network analyzer (VNA) front end consisting of a resistive bidirectional bridge, downconversion mixers, programmable IF amplifiers and filters, and a highly flexible local oscillator (LO) interface. The bridge provides >14 dB of directivity up to 17 GHz. The primary transmission line from RFIN to RFOUT is wideband matched to 50 Ω with only 1.1 dB loss at 9 kHz...
