ATEK274N4 Block Diagram
The ATEK274N4 is a wideband high power GaN MMIC SPDT reflective switch offering a 20W power handling operating from 6 to 18 GHz. The switch is fabricated on a Gallium Nitride on SiC process to enable high operating output power levels while maintaining fast switching speeds and minimal loss.The ATEK274N4 exhibits insertion loss of 0.7dB while switching 20W over the full X-band frequency range with 0.3dB compression. The switch has excellent return loss and provides 35dB typical isolation.The ATEK274N4 is housed in a compact 4x4mm SMD package with input and output matched to 50 ohms internally.Evaluation Board, bare die, custom package, and module options are available upon request.
