Description
M/A-COM’s MD54-0004 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
MD54-0004 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 cellular receivers and transmitters, and 900 MHz ISM
band applications.
The MD54-0004 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
+25 dBm. DC bias is not required.
M/A-COM’s MD54-0004 is fabricated using a mature
1-micron GaAs process. The process features full IC
passivation for increased performance and reliability.

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 indicat-
ed 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.
