ATEK256N3 is a wideband absorptive SPDT switch with low loss and high isolation. Frequency of operation starts from low frequencies close to DC, goes up to 20 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 3×3 mm surface mount package.
Evaluation Board, bare die, custom package, and module
options are available upon request.
