As displayed here, the PAT series attenuators have very good insertion loss (attenuation) and voltage standing wave ratio up to 10GHz. The PAT series are excellent attenuators if the customer requires up to 10GHz. However, the electronics world is moving faster and faster with new wireless communications including IoT and 5G all requiring higher frequencies. Responding to these market demands, Susumu is introducing the ATS series as an answer to these higher frequency trends.
