Applications Information
Input Matching
For optimum performance, input matching is required.
The MAX2654/MAX2655/MAX2656 require a simple LC
matching network. The Typical Operating Circuit shows
the recommended input matching networks. These val-
ues are optimized for best simultaneous gain, noise fig-
ure, and return loss performance. S-Parameter data can
be found on the Maxim website at www.maxim-ic.com.
Layout Issues
A properly designed PC board is essential to any RF-
microwave 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 PC board uses a topside RF
ground, connect it directly to all GND pins. For a board
where the ground plane is not on the component layer,
connect the GND pins to the board with a multiple vias
close to the package.
For MAX2654, connect Pin1 to the PC board ground
plane through a 0.017in x 0.035in line.
