MAX19997A
Dual, SiGe High-Linearity, 1800MHz to 2900MHz
Downconversion Mixer with LO Buffer
Power-Supply Bypassing
Proper voltage supply bypassing is essential for high-
frequency circuit stability. Bypass each V CC pin with
the capacitors shown in the Typical Application Circuit.
Exposed Pad RF/Thermal Considerations
The exposed pad (EP) of the MAX19997A ’s 36-pin
path to the die. It is important that the PCB on which the
MAX19997A is mounted be designed to conduct heat
from the EP. In addition, provide the EP with a low-
inductance path to electrical ground. The EP MUST be
soldered to a ground plane on the PCB, either directly
or through an array of plated via holes.
TQFN-EP package provides a low thermal-resistance
