Fixed Attenuator Pads
SemiGen RF/microwave fixed attenuator pads feature precise resistor films and superior metallization 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 required. Wire bondable top side contacts for RF in/out make these ideal for standard RF/microwave assembly techniques.
