The MD54-0005 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 basestation and portable systems. The MD54-0005 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 passivation for increased performance and reliability. .008 .043 +- .004 1.10 + 0.20 - 0.10 .002± .002 0.05± 0.05 .031 + .004 - .007 0.80 + 0.10 - 0.18 .006 + .004 - .002 + 0.10 0.15 - 0.05 .016 + .004 - .002 0.40 + 0.10 - 0.05 .008 MIN 0.20 MIN Ordering Information Part Number MD54-0005 MD54-0005TR MD54-0005SMB Package SOT-363 Plastic Package 1 Forward Tape and Reel Designer’s Kit 1.
