Precaution of GND line The GND points of input side GND and N.F side GND in each amplifier must be arranged at the preamplifier side. (Figure 1) The input side GND point and the N.F side GND point must be arranged near each other to have no impedance. Figure 1 2. About radiation (1) The capacitance between the output and GND in preamplifier, buffer amplifier and power amplifier must be arranged near to this IC. The ra...
