    Abstract: Adjustable broadband impedance matching circuits using tapered lines A self-adjusting broadband impedance transforming circuit for matching a load port 4 to a source port 2 comprises a tapered transmission line 10 and at least one variable impedance 12 coupled to the line and adjustable by a controller 20 in dependence on the output of an impedance mismatch detector 21. The controller may access a look-up table to find initial adjustable impedance settings for a given signal frequency, the controller then providing fine adjustment in conjunction with the mismatch detector 21. The variable impedances may comprise semiconductor varactors, MEMS varactors, MEMS switched capacitors, ferroelectric capacitors, a bank of switched MEMS capacitors, or PiN diodes. The mismatch detector 21 maydetect voltage level, phase, or power. The variable impedances may be connected to the line, to its ends ( figure 3) or between line sections ( figure 4), and may be connected via stubs ( figures 8 and 9). The tapered line may comprise multiple short sections of constant width.
