MAX2667/MAX2669
GPS/GNSS Ultra-Low-Noise-Figure LNAs
Shutdown
The devices include a shutdown feature to turn off the
entire chip. A logic-high must be applied to the RFOUT/
( SHDN) pin using a 25kΩ external resistor to place the
part in active mode, and a logic-low to place the part in
shutdown mode.
Applications Information
A properly designed PCB is essential to any RF micro-
wave circuit. Use controlled-impedance lines on all
high-frequency inputs and outputs. Bypass V CC with
decoupling capacitors located close to the device. For
long V CC lines, it may be necessary to add decoupling
capacitors. Locate these additional capacitors further
away from the device package. Proper grounding of
the GND_ pins is essential. If the PCB uses a topside
RF ground, connect it directly to the GND_ pins. For a
board where the ground is not on the component layer,
connect the GND_ pins to the board with multiple vias
close to the package.
