Description

M/A-COM’s MAMXSS0012 is a passive mixer that achieves the performance of a double balanced diode mixer in a lead-free SOT-25 package. The MAMXSS0012 is ideally suited for use where high level RF signals and very wide dynamic range are required. Typical applications include frequency up/ down conversion, modulation, and demodulation in receivers and transmitters for base station and portable systems. The MAMXSS0012 employs GaAs FETs as mixing elements to achieve a very wide dynamic range in a low cost plastic package. The mixer operates with LO drive levels of +3 dBm to +8 dBm. The LO port may be externally tuned for operation in various frequency bands. M/A-COM's GaAs IC is fabricated using a mature 0.5 micron gate length GaAs MESFET process. The process features full pass ivation for increased performance and reliability. Part Number Package MAMXSS0012 Bulk Packaging MAMXSS0012TR-3000 3000 piece reel MAMXSS0012SMB Designers Kit

RoHS Compliant Cross Section View Recommended PCB Configuration Layout View The PCB dielectric between RF traces and RF ground layers should be chosen to reduce RF discontinuities between 50 Ω lines and package pins. M/A-COM recommends an FR-4 dielectric thickness of 0.008” (0.2 mm) yielding a 50 Ω line width of 0.015” (0.38 mm). The recommended metalization is 1 oz. copper.
