Abstract
A voltage-controlled oscillator in which a tunable resonator (102) having a first port (132) and a second port (106) is disclosed. In one embodiment, the tunable resonator is a series resonating circuit having low driving and load impedances. A power gain element (108) is coupled to the first port and the second port, and an output port (110) is coupled to the power gain element and the second port. The first impedance at the first and second ports is less than approximately ten ohms. The voltage-controlled oscillator is capable of generating a signal at the output port of greater than approximately half a watt.
