These smp terminations (aka smp loads) bodies are made of BeCu (female) and Stainless Steel (Male). SMP Load terminations interface with smp and gpo™(trademark of Gilbert/Corning)). While an smp connector is good to 40ghz, the performance of an smp termination is sometimes limited by the load resistive material. We offer smp terminations rated to 18, 27, & 40ghz. Both SMP Female termination and Male terminations are offered.. SMP Terminations are compatible with GPO® terminations ( trademarked by Corning Gilbert).
