ATEK822P4 Block Diagram
ATEK822P4 is a tunable low pass filter with low in band loss and high rejection. Filter is controlled by 4-bit GPIO control interface.15 filter covering from 0.35 to 1.1 GHz frequency band, and an additional state for wideband 1.7 GHz LPF. 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 4x4 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.
