MAMXSS0012 Low Cost MMIC Mixer Rev. V2 800 - 1000 MHz Features Functional Schematic Input Power 1 dB Compression: +15 dBm C1 High LO to RF Isolation: 35 dB LO Drive Level: +3 to +8 dBm L1 DC - 200 MHz 3 dB IF Bandwidth R1 Does not require DC bias Lead-Free SOT-25 Package 100% Matte Tin Plating over Copper 3 2 1 Halogen-Free Green Mold Compound 260C Reflow Compatible RoHS* Compliant Version of MD54-0005 Description M/A-COMs MAMXSS0012 is a passive mixer that achieves the performance of a double balanced diode mixer in a lead-free SOT-25 package. The 4 5 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 Pin Configuration portable systems. Pin No. Function Pin No. Function 1 LO 4 RF The MAMXSS0012 employs GaAs FETs as mixing elements to achieve a very wide dynamic range in a 2 Ground 5 IF low cost plastic package. The mixer operates with 3 Ground LO drive levels of +3 dBm to +8 dBm. The LO port may be externally tuned for operation in various frequency bands. 2 External Circuitry Parts List M/A-COM s GaAs IC is fabricated using a mature Ref. 0.5 micron gate length GaAs MESFET process.
