M1-638 The M1-638 is a Microlithic double balanced mixer. As with all Microlithic mixers (patent pending), it features excellent conversion loss, isolations, and spurious performance across a broad bandwidth and in a miniaturized form factor. Accurate, nonlinear software models are available for Microwave Office through the Marki Microwave PDK. The M1-638 is available as a wire bondable chip or in a connectorized package. The M1-638 is an excellent alternative to Marki Microwave M9 mixers packaged in drop-in carriers such as the ES carrier. Features Compact Chip Style Package (.152 x.9 x.15 ) CAD Optimized for Superior Isolation and Spurious Response Broadband Performance Excellent Unit-to-Unit Repeatability Fully nonlinear software models available with Marki PDK for Microwave Office RoHS Compliant Electrical Specifications - Specifications guaranteed from -55 to +1 C, measured in a 5Ω system.

Page 5 M1-638 Downconversion Spurious Suppression Spurious data is taken by selecting RF and O frequencies (+mo+nrf) within the 6 to 38 GHz RF/O bands, which create a 1 MHz IF spurious output. The mixer is swept across the full spurious band and the mean is calculated. The numbers shown in the table below are for a -1 dbm RF input. Spurious suppression is scaled for different RF power levels by (n-1), where n is the RF spur order. For example, the 2RFx2O spur is 6 dbc for a -1 dbm input, so a -2 dbm RF input creates a spur that is (2-1) x (-1 db) db lower, or 7 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 -1 dbm IF input. Spurious suppression is scaled for different IF input power levels by (n-1), where n is the IF spur order. For example, the 2IFx1O spur is typically 65 dbc for a -1 dbm input, so a -2 dbm IF input creates a spur that is (2-1) x (-1 db) db lower, or 75 dbc.
