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 low frequencies, increasing to 1.
8 dB loss at 20 GHz.
The ADL5960 supports several different LO interface configurations that simplify the clocking design of a vector network analyzer (VNA) solution as well as the interfacing of the device to an analog-to-digital converter (ADC).
The frequency divider and multipliers in the LO interface enable measurement sweeps beyond the operating frequency range of the LO source, enabling operation over the full 20 GHz frequency range of the ADL5960 using a 6 GHz synthesizer.
The IF frequency offset mixer, driven through the offs...
