The MD54-0003 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, demodulation in systems such as base station receivers and transmitters for DCS1800, PCS and PHS applications. The MD54-0003 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 +11 dBm to +23 dBm. No DC bias is required. M/A-COM's MD54-0003 is fabricated using a mature 1-micron GaAs process. The process features full IC passivation for increased performance and reliability. .0532-.0688 (1.35-1.75) 0-8 -C.0040-.0098 (0.10-0.25) .013-.020 TYP.

Functional Diagram3 1 GND RF GND GND 4 5 8 GND IF LO R GND L C Harmonic of RF (m) The spurious table shows the spurious signals resulting from the mixing of the RF and LO input signals, assuming down conversion. Mixing products are indicated by the number of dB below the conversion loss. The lower frequency mixing term is shown for two different RF input levels. The top number is for an RF input power of -5 dBm, the lower number is for -15 dBm. |mFRF - nFLO|, RF = -5 dBm |mFRF - nFLO|, RF = -15 dBm RF Frequency = 1850 MHz LO Frequency = 1710 MHz 3.
