PC1678G,
P
PC1679G
The gain vs. frequency characteristics of the
P
PC1678/1679 with various inductance values are measured using a
manually wound coil. Figure 4-3 shows the measured characteristics. In the case of these ICs, the gain at low
frequencies and high frequencies increases and wide band is achieved when the inductance value is increased, and
the frequency band near the resonance frequency becomes narrow when the inductance value is decreased.
