Layout
The MAX2204 is not particularly sensitive to the layout,

TO ANT
since it only needs 5dBm for maximum output voltage.
However, there are two areas that need attention: the
GND pin and the supply bypassing. The GND pin should
be connected to the PCB ground with a GND via as
close as possible, and the supply bypass capacitor

Figure 2. Typical Application Circuit Using Resistive Tapping
from a Power Amplifier
The MAX2204 has high input impedance to allow
for high-value resistive tapping from a power amplifier.
This coupling method is the lowest cost and lowest
power loss when used with an isolator. See Figure 2 for
the typical application circuit.
The MAX2204 input impedance over frequency is listed
in Table 1.
