ATEK258P4 Block Diagram
ATEK258P4 is a wideband absorptive SP8T switch with low loss and high isolation. Frequency of operation starts from low frequencies close to DC, goes up to 12 GHz. Operating with positive supply voltage and switch state is chosen by positive voltage control interface. Eliminates the need for external negative bias circuitry for the user. RF input outputs are matched to 50 ohms internally. Switch is housed in a compact low cost 4x4 mm surface mount package. Evaluation Board, bare die, custom package, and module options are available upon request.
