Functional Schematic
Description
The MAMX-008611 is a floating FET mixer with an
on-chip LO amplifier. The LO drive for the MAMX-
008611 can range from –5 to +5 dBm without
severely impacting the mixer’s performance. The
MAMX-008611 is ideally suited for cellular band
communications handsets’ that can provide only
minimal amounts of LO drive. Typical applications
include frequency up/down conversion and IQ
modulation and demodulation in digital receivers
and transmitters.
The MAMX-008611 utilizes a patented “floating-
FET” architecture. The on-chip LO amplifier allows
the MAMX-008611 to operate with as little as –5
dBm of LO drive making it an ideal choice for low
power portable designs.
The MAMX-008611 is fabricated using M/A-COM’s
0.5 micron low noise GaAs MESFET process. This
process features full passivation for increased
performance and reliability. The MAMX-008611 is
100% RF tested to ensure superior performance
specification compliance.

discontinuities between 50
Ω
lines and package
pins. M/A-COM recommends an FR-4 dielectric
thickness of 0.008” (0.2 mm) yielding a 50
Ω
line
width of 0.015” (0.38 mm). The recommended
metallization thickness is 1 oz. Copper.
