Thin film attenuator
1. Overview
The thin-film attenuator has low parasitic parameters, the use frequency is as high as 18GHz; it is moisture-proof and forms a self-passivating protective film; it is suitable for gold wire bonding. It is widely used in radio frequency, microwave and millimeter wave communications, optical communications and other fields.
At present, 6 series of attenuation films have been developed, with hundreds of varieties. Take the AT150504-X type attenuator as an example to introduce:
