Microwave ovens are everywhere, and at the heart of them is a magnetron — a device that creates microwaves. [DiodeGoneWild] tore one apart to show us what was inside and how it works.

The magnetron has failed ... It generally doesn’t make sense to repair a microwave that’s more than 7 years old. Instead, look at new models that may be more energy-efficient or offer useful ...

In this article, we’re going to look beyond the typical magnetron / HV power supply / electronics and instead focus on some other peculiarities of microwave reactors than you might not know.

The post-war period saw a proliferation in magnetron applications, beginning with the invention of the microwave oven in 1946 and continuing today with base stations for LTE and 5G networks.
