Knowles ATT A-Series Attenuators
Knowles ATT A-Series Attenuators are wideband, surface-mount (SMD) attenuators that offer high accuracy and power handling in a compact package (2.03mm x 1.65mm x 0.30mm). The ATT A-Series offers excellent attenuation flatness and standard attenuation values from 0dB to 20dB. 50Ω matched RF inputs and outputs enable integration into RF signal chains. These Knowles attenuators are designed for a variety of applications, including radar systems, electronically steered phased-array antennas (ESAs), transmit/receive (T/R) modules, wireless infrastructures, satellite communications, and RF test and measurement.
