Problems Concerning Wideband AGC
Because the LA1136N and the LA1137N offer many sophisticated functions, a number of their pins are dual-purpose pins. An
example is pin 3 (on both the LA1136N and the LA1137N), which serves both as the wideband AGC input pin and the antenna
dumping pin diode drive pin. As a result, particular attention must be given to the wiring pattern layout, since feedthrough of other
signals as shown in the figure below can cause AGC to operate without input, resulting in reduced sensitivity.
RF characteristics at 600 kHz
RF characteristics at 1 MHz
RF characteristics at 1.4 MHz
Avoid direct
feedthrough from the
RF amplifier to the
pin 3 line.
