Benefits of PAT series
Three precision resistors are integrated as an attenuator. Therefore, precision attenuation can be easily achieved with this attenuator.
Because 3 elements are integrated in a small area, parasitic capacitance and inductance are minimized and desired attenuation can be easily attained.
One attenuator can replace 3 discrete resistors, which contributes miniaturizing the circuit and makes the circuit more reliable
Three resistive elements are integrated inside of this chip attenuator. If you use discrete resistors to construct an
attenuator, 3 resistors are needed. The merits of one attenuator displacing 3 resistors are:
