ATEK357P4 Block Diagram
ATEK357P4 is a wideband 5-bit Digital Step Attenuator with 30 dB attenuation range. Attenuator frequency of operation goes down to Low Frequency close to DC and 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 4x4 mm low cost SMD package, input and outputs are matched to 50 ohms internally. Evaluation Board, bare die, custom package, and module options are available upon request.
