TNP #16 – Teardown, Repair & Analysis of a few mm-Wave (26GHz – 40GHz) Amplifier Modules

In this episode Shahriar takes a close look at a few mm-wave amplifier modules which have failed. The amplifiers cover a few frequency ranges up to 40GHz. The measure S-Parameters reveals a serious problem with the amplifiers. The teardown of the module is presented along with microscope closeups of various devices and integrated circuits used in its construction.
A broadband amplifier is also examined with a simpler problem. A broken DC power connector is replaced which brings the unit back to life showing 18dB of gain with better than 25GHz 2dB bandwidth.​​​
