Description

M/A-COM’s MD54-0006 is a passive mixer that achieves the
performance of a double balanced diode mixer in an ultra-miniature
SOT-25 package. 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 MD54­0006 is 100 % RF tested to ensure performance specification
compliance.

The PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 5 0 Ω
lines and package pins. M/A-COM recommends an FR-4
dielectric thickness of 0.008” (0.2 mm) yielding a 5 0 Ω line
width of 0.015” (0.38 mm). The recommended metalization
thickness is 1 ounce copper.

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 relative to the IF. The lower frequency mixing
term is shown for two different RF input levels. The upper number is for an RF input power of 0 dBm; the
lower number is for an RF level of -10 dBm.
