Abstract
PURPOSE: To increase the dielectric strength and the reliability of the diplexer by setting the electric length between the antenna terminal and LPF and BPF each to the odd-fold value of 1/4 wavelength to the reception and transmission waves respectively.
CONSTITUTION: LPF1 and BPF2 are used for the transmitting and receiving filters each for formation of the diplexer. And the electric length between antenna terminal 4 and LPF1 to an odd-fold value of 1/4 wavelength to the reception wave; while the electric length between the antenna terminal and BPF2 is set to an odd- fold value of 1/4 wavelength to the transmission wave. As a result, both the dielectric strength and the reliability can be increased for the diplexer.
