ADL5961 Datasheet (Analog Devices) - 9kHz to 26.5GHz Integrated Vector Network Analyzer Front End

ADL5961, 9kHz to 26.5GHz Integrated Vector Network Analyzer Front End

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
