Marki Microwave Attenuators provide fixed signal attenuation for RF and microwave systems operating up to 70GHz. The portfolio combines high attenuation accuracy, optimal return loss, and extremely low unit-to-unit variation. The devices feature ultra-compact surface-mount and chip-scale packages that support space-constrained, high-density system designs.
