ATEK356P3 Block Diagram
ATEK356P3 is a wideband 1-bit Digital Step Attenuator with 9 dB attenuation range. Attenuator frequency of operation goes down to Low Frequency close to DC and goes up to 14 GHz. Usable bandwidth goes up to 20 GHz. Bias and control voltages of the attenuator are positive, which eliminates the need for negative voltage rails. Attenuator is housed in compact 3x3 mm low cost SMD package, input and output matched to 50 ohms internally. Evaluation Board, bare die, custom package, and module options are available upon request.
