Figure 2. Controller-Mode Typical Application Circuit
detected signal with a reference voltage determined by
V SET . The integrator, acting like a comparator, increas-
es or decreases the voltage at OUT, according to how
closely the detected signal level matches the V SET ref-
erence. The MAX2015 adjusts the power of the PA to a
level determined by the voltage applied to SET. With R1 =
0 ? , the controller mode slope is approximately
19mV/dB (RF = 100MHz).

Layout Considerations
As with any RF circuit, the layout of the MAX2015 circuit
affects the device’s performance. Use an abundant num-
ber of ground vias to minimize RF coupling. Place the
input capacitors (C1, C2) and the bypass capacitors
(C3–C6) as close to the IC as possible. Connect the
bypass capacitors to the ground plane with multiple vias.
