Very Low Current: 7 mA
Single Ended Ports, 50-Ohm Impedance
Small Plastic Package: SOT-26
Description
The MD57-0002 is a passive MMIC mixer with an
on-chip LO buffer amplifier that allows the
MD57-0002 to operate with LO drive levels of -5
dBm to +5 dBm. The MD57-0002 features single
ended ports and does not require the use of external
baluns. All ports are 50-ohm impedance.
The MD57-0002 is ideally suited for up and down
frequency convertor applications in DCS1800,
PCS1900, PHS and 3G wireless communications
equipment requiring low LO power, high linearity,
low conversion loss and very low current
consumption.
The MD57-0002 is fabricated using a 0.5 micron
gate length GaAs MESFET process. This process
features full passivation for increased RF
performance and enhanced reliability.

PCB dielectric between RF traces and RF ground layers
should be chosen to reduce RF discontinuities between 50ohm lines and package pins. M/A-COM recommends an FR4 dielectric thickness of .008 (0.2 mm) yielding a 50-ohm line
width of 0.015” (0.38 mm). The recommended metalization
is 1 oz. copper.
