Abstract
PURPOSE:To attain mathcing with a low-impedance load by connecting a capacitor between a transformer and mechanical resonator and then by connecting a coil to a transformer terminal opposing to the terminal to which the mechanical filter is connected. CONSTITUTION:The output terminal of mechanical resonator B is connected via capacitor C03 to the input terminal of transformer Trs2, whose output terminal is connected to a load via coil L0. The capacitor is interposed between the mechanical resonator and transformer and the coil is connected to a terminal different with that connected to the mechanical filter via the capacitor. It is made possible to constitute this unit by using a relative-small capacitor and inductance. Therefore, a capacitor and inductance large in Q can easily be obtained a filter can be obtained which has a little loss on the whole.
