ATEK359P4 Block Diagram
ATEK359P4 is a 5-bit Digital Step Attenuator with 31 dB attenuation range. Attenuator frequency of operation goes down to 500 MHz and goes up to 4 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 output matched to 50 ohms internally. Evaluation Board, bare die, custom package, and module options are available upon request.
