TNP #18 – Repair & Analysis of a W-Band (75-110GHz) WR-10 12dBm Power Amplifier Module

In this episode Shahriar takes a look at a non-functional W-Band (75-110GHz) power amplifier module with WR-10 waveguide ports. A quick inspection reveals a broken DC connector which can be easily repaired. Since a W-Band VNA or source is not available, the amplifier’s excess noise is instead measured using an external mixer and a Keysight MXA-B. The noise power spectral density shows the the amplifier is likely functional with the expected noise and gain.
