Thin film attenuator

  • 1. Overview
The film attenuator has low parasitic parameters and high frequency of use up to 18GHz. Moisture-proof, forming self-passivating protective film; Suitable for bonding of gold wire. Widely used in radio frequency microwave millimeter wave communication, optical communication and other fields.

At present, we have developed 6 series of attenuation sheets with over 100 varieties. The following is an example of AT150504-X attenuator:
