Fixed Attenuator Pads
SemiGen RF/microwave fixed attenuator pads feature precise resistor films and superior metalization resulting in superior performance and consistency. Our advanced thin-film technology allows our parts to have full side wraps for SMT installation and a complete grounding backside for ease in attachment, as no ground bonding is requried. Top side contacts for the input and output make these ideal for standard RF/microwave assembly techniques. They are available as MIL PRF 38534 “H” & “K” space screened units. Custom values are easy to fabricate and design allowing users to design in a specific value of choice.
