| MD54-0005 Low Cost MMIC Mixer 800 - 1000 MHz Features * * * * * * Input Power @ 1 dB Compression: +15 dBm High LO to RF Isolation: 35 dB LO Drive Level: +3 to +8 dBm DC - 200 MHz 3 dB IF Bandwidth Does not require DC bias Ultra-Miniature SOT-25 Plastic Package 3 2 Rev. V4 Functional Schematic C1 L1 R1 Description M/A-COM's MD54-0005 is a passive mixer that achieves the performance of a double balanced diode mixer in an ultra-miniature SOT-25 package. 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 pack-age. 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. 1 4 5 Pin Configuration Pin No. 1 2 3 Function LO GND GND Pin No. 4 5 Function RF IF External Circuitry Parts List 2 Ref.
