Teardown of Cisco / Atlanta Scientific Cable TV combining amplifier. These small amplifiers are used in receiver stations with combining amplifiers to send out the different channels on a single cable. In houses a splitter is used to receive this signal and distribute to more households. Historically CATV is short for Community Antenna TV. A

A guide on how to calculate gate drive transformer, how to wind gate drive transformers and test gate drive transformers. Gate drive transformers are also called GDT for short. The most important aspects is insuring low leakage inductance, no core saturation and having enough peak drive current available for your MOSFETs or IGBTs. This video
