Marki Microwave Attenuators
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.
The Marki Microwave Attenuators include attenuation values ranging from low-loss through-line options to 20dB devices. Available package families support different frequency, power-handling, attenuation-flatness, and PCB-footprint requirements. These characteristics make the attenuators ideal for airborne applications, high-channel-count systems, and SWaP-C.
