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 4×4 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.
