• Manufacturer Part Number: MAX9994
• Description: 1700MHz to 2200MHz Downconversion Mixer
• Manufacturer: Maxim Integrated Products

The exposed paddle (EP) of the MAX9994’s 20-pin thin
QFN-EP package provides a low thermal-resistance
path to the die. It is important that the PC board on
which the MAX9994 is mounted be designed to con-
duct heat from the EP. In addition, provide the EP with a
low-inductance path to electrical ground. The EP MUST
