Page MMIQHSM The MMIQHSM is a miniaturized, surface-mount multi-octave.7. GHz IQ mixer. It features matched double balanced mixers connected with an integrated LO hybrid and power divider. It can be used for either upconversion or downconversion. Applications include communications or radar systems with advanced digital modulation formats and phase modulated signals, test and measurement, or electronic warfare. Image reject or single sideband modulation with excellent suppression is possible with use of an external IF quadrature (9 ) hybrid. Features mm QFN Surface-Mount Package CAD Optimized for Superior Isolation, Spurious Response, and Image Rejection/Sideband Suppression Broadband Performance Excellent Unit-to-Unit Repeatability Fully nonlinear software models available with Marki Circuit Models for Microwave Office RoHS Compliant Electrical Specifications - Specifications guaranteed from to + C, measured in a Ω system.

Page 8 Downconversion Spurious Suppression MMIQHSM Spurious data is taken by selecting and LO frequencies (+mlo+n) within the /LO bands, to create a spurious output within the IF band. The mixer is swept across the full spurious band and the mean is calculated. The numbers shown in the table below are for a - dbm input. Spurious suppression is scaled for different power levels by (n- ), where n is the spur order. For example, the xlo spur is 8 dbc for a - dbm input, so a dbm input creates a spur that is (-) x (- db) db lower, or 9 dbc.

The mixer is swept across the full spurious output band and the mean is calculated. The numbers shown in the table below are for a - dbm IF input. Spurious suppression is scaled for different IF input power levels by (n-), where n is the IF spur order. For example, the IFxLO spur is typically 78 dbc for the A configuration for a - dbm input, so a dbm IF input creates a spur that is (-) x (- db) db lower, or 88 dbc.
