1 1.33. GHz Image Reject Mixer November 27 Rev 2Nov7 M11QH Features Fundamental Image Reject Mixer 9. Conversion Loss 2. Image Rejection +2. m Input Third Order Intercept (IIP3) 4x4 mm, QFN ROHS Compliant General Description Mimix Broadband s GHz GaAs MMIC fundamental image reject mixer with high linearity has a conversion loss of 9. with a 2. image rejection across the band. I and Q mixer outputs are provided and an external 9 degree hybrid is required to select the desired sideband. This MMIC uses Mimix Broadband s.1 µm GaAs PHEMT device model technology, and is based upon electron beam lithography to ensure high repeatability and uniformity. The device comes in a lowcost 4x4 mm QFN surface mount plastic package. This device is well suited for Millimeterwave PointtoPoint Radio, LMDS, SATCOM and VSAT applications.

5 1.33. GHz Image Reject Mixer November 27 Rev 2Nov7 App Note [3] USB/LSB Selection LSB USB M11QH For Upper Side Band Operation (USB): With IF1 and IF2 connected to the direct port (º) and coupled port (9º) respectively as shown in the diagram, the USB signal will reside on the isolated port. The input port must be loaded with ohms. IF2 IF1 An alternate method of Selection of USB or LSB: USB For Lower Side Band Operation (LSB): With IF1 and IF2 connected to the direct port (º) and coupled port (9º) respectively as shown in the diagram, the LSB signal will reside on the input port. The isolated port must be loaded with ohms. Note: The coupled port can be used as an alternate input but the port location of the Coupled and Direct ports reverse.
