Functional Schematic
• -5 to +5 dBm LO Drive Level
• High Isolation, 28 dB LO to RF
• SOT-26 package
Description
The MD57-0001 is a floating FET mixer with an onchip LO amplifier. The LO drive for the MD57-0001
can range from –5 to +5 dBm without severely
impacting the mixer’s performance. The MD57-0001
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 MD57-0001 utilizes a patented “floating-FET”
architecture. The on-chip LO amplifier allows the
MD57-0001 to operate with as little as –5 dBm of LO
drive making it an ideal choice for low power
portable designs.
The MD57-0001 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 MD57-0001 is
100% RF tested to ensure superior performance
specification compliance.

PCB Cross Section View
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 dielectric
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.
