Description
The MD57-0001 is a floating FET mixer with an on-chip LO
amplifier. The LO drive for the MD57-0001 can range from -5 to
+5 dBm without severly 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.

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
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.

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 relative to the IF level.
The lower frequency mixing term is shown for two different
RF input levels.
The RF frequency is 900 MHz, the LO frequency is 730
MHz.
