An adjustable unequal power divider design

An adjustable unequal power divider design is proposed. The design replaces two transmission lines of the two-section power divider by two T-equivalent circuits. By tuning the capacitors in the T-equivalent circuits, the power ratio can change from 1:2 to 1:3 or from 1:3 to 1:2. The circuit has been simulated by EM simulators and verified the performance by fabricated and measured the prototype layout circuit.
