| Low Cost MMIC Mixer, 2.1 - 2.7 GHz V 1.0 MD54-0007 Features * * * * * * MMDS and WLAN Applications +18 dBm Input 1 dB Compression Point Greater than 20 dB LO to RF Isolation +13 dBm LO Drive Level No DC Bias Required Ultra-Miniature SOT-25 Plastic Package Functional Schematic RF 1 5 GND 4 IF 2 3 LO GND Description M/A-COM's MD54-0007 is a passive mixer that achieves the performance of a double balanced diode mixer in an ultra-miniature SOT-25 package. The MD54-0007 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 MD54-0007 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 +13 dBm to +18 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.
