Selection
When functioning as a PA controller, the MAX4001
requires some capacitance to maintain loop stability.
Global System for Mobile (GSM) applications require a
control-loop bandwidth of at least 150kHz. A 2200pF
capacitor, C4, is installed to obtain this control-loop
bandwidth. Refer to the Gain and Phase vs. Frequency
graph in the Applications Information section of the
MAX4000/MAX4001/MAX4002 data sheet for alternative
capacitor values.
The MAX4001 can be replaced with the MAX4000 to
allow an input range of -45dBm to 0dBm into 50Ω. The
modifications required are as follows:
1) Replace U1 with a MAX4000EBL.
2) Replace C6 with a 0Ω (0402) resistor.

DESCRIPTION
MAX4001 Evaluation Kit
The MAX4001 can be replaced with the MAX4002 to
allow an input range of -30dBm to +15dBm in 50Ω. The
modifications required are as follows:
1) Replace U1 with a MAX4002EBL.
A good PC board is an essential part of RF circuit
design. The MAX4001 EV kit PC board can serve as a
guide for laying out a board using the MAX4000/
MAX4001/MAX4002. Keep traces carrying RF signals
as short as possible to minimize radiation and insertion
loss due to the PC board. Each VCC node on the PC
board should have its own decoupling capacitor. This
minimizes supply coupling from one section of the PC
board to another. Using a star topology for the supply
layout, in which each VCC node in the circuit has a
separate connection to the central VCC node, can fur-
ther minimize coupling between sections of the PC
board.
