Description
M/A-COM’s MD54-0003 is a passive mixer that
achieves the performance of a double balanced
diode mixer in a low cost surface mount plastic
SOIC-8 lead package. 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.

Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
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.
