ATEK951P4 is a wideband low noise amplifier with bypass option covering 0.01 to 8 GHz frequency range. Amplifier operational low frequency range can be extended to lower frequencies by increasing external component values.
Amplifier provides flat gain and low noise over wideband with single supply voltage. Bypass state is controlled with positive voltage, eliminating the need for negative voltage rails. This allows users to easily realize wideband receiver frontends.
Amplifier 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.
