MFC-PO13811-QDG
RoHS COMPLIANT
37-40GHz Down converter
GaAs Monolithic Microwave IC in SMD package Description
The MFC-PO13811-QDG is a multifunction part, which integrates a balanced cold FET mixer, a time two multiplier, and a RF LNA. It is designed for a wide range of applications, typically commercial communication systems. The circuit is manufactured with a PM-HEMT process, 0.25m gate length, via holes through the substrate and air bridges.

The DC connections do not include any decoupling capacitor in package, therefore it is mandatory to provide a good external DC decoupling on the PC board, as close as possible to the package. The SMD leadless package has been designed for high volume surface mount PCB assembly process. A typical footprint is proposed for the PCB (motherboard) in the previous drawing. For the mounting process standard techniques involving solder paste and a suitable reflow process can be used. For further details, see application note AN0017.
