ATEK890P4 is a tunable high pass filter with low in band loss and high rejection. Filter is controlled by 4-bit GPIO control interface. 16 filters covering from 1.00 to 1.95 GHz frequency band.
Filter is developed in highly repeatable MMIC manufacturing process, which results in minimal part to part variation.
Bias and control voltages of the filters are positive, which eliminates the need for negative voltage rails.
Filter is housed in compact 4×4 mm low cost SMD package. Input and output are matched to 50 ohms internally.
Evaluation Board, bare die, custom package, and module options are available upon request.
