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.

The PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 50
Ω
lines and package pins. M/A-COM recommends an FR-4 dielec-
tric thickness of 0.008”(0.2 mm) yielding a 50
Ω
line width of
0.015”(0.38 mm). The recommended metalization thickness is
1 oz. copper.

The spurious table shows the spurious signals resulting from the
mixing of the RF and LO input signals assuming down conver-
sion. 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.
