Abstract:
A novel planar dual-band microstrip power divider is proposed in this paper. The circuit is composed of two sections of transmission line, short-circuited stub line and planar resistor, which can provide high isolation and good amplitude balance simultaneously at two frequencies. The closed-form equations are derived,and the design procedures of dual-band power divider are given. To Certify the validity, a proposed power divider was fabricated and measured at 950 MHz and 2200 MHz which might be applied to M and CDMA systems. Both theoretical and simulated results are given, which are in good agreement with the measured results.
