CHS2411-QDG 23-26GHz Reflective SP4T Switch GaAs Monolithic Microwave IC in SMD leadless package Description The CHS2411-QDG (CHS2412-QDG, see Note) is a monolithic reflective SP4T switch in K-Band. Positive supply voltage only is required. The circuit is manufactured with a standard pHEMT process, 0.25m gate length, via holes through the substrate, air bridges and electron beam gate lithography. The chip is delivered in a 24 Leads RoHS compliant QFN 4x4 package. Functional Block Diagram Main Features UMSUMSUMSUMSUMSUMS Low insertion loss: 2.9dB Typ.
