The MD54-0006 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 MD54-0006 uses FETs as mixing elements to achieve 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 MD54-0006 is fabricated using a mature 0.5 micron gate length GaAs MESFET process. The process features full passivation for increased performance and reliability. The MD54-0006 is 100% RF tested to ensure performance specification compliance.
