The Infineon silicon germanium 24 GHz twin IQ receiver MMIC is accommodating two separate homodyne quadrature down conversion chains, operating from 24.0 to 24.25 GHz. LO buffer amplifiers are included to relax LO drive requirements and individual LNAs provide low noise figures. RC polyphase filters are used for LO quadrature phase generation. The circuit is manufactured in a 0.18μm SiGe:C technology offering a cut-off frequency of 200 GHz. The MMIC is packaged in a 32 pin leadless RoHS compliant VQFN package.
