Bandwidth high power voltage controlled oscillator circuit and package structure

Abstract

The application provides a bandwidth high-power voltage-controlled oscillator circuit, which works in cooperation with a frequency selection unit, an oscillation unit and an amplification unit: the frequency selection unit is connected with an input unit, can control an output frequency according to an input voltage, and solves the problem of narrow bandwidth of a high-power scheme; the oscillation unit forms a feedback loop with a field effect tube and a feedback network, receives a frequency selection unit signal and generates a first signal, and guarantees stable generation of an oscillation signal; the power tube gate of the amplification unit is connected with the field effect tube, the drain is connected with an output unit, the first signal is amplified into a high-power second signal, and the power defect of a low-power scheme is compensated. Meanwhile, the structure of direct correlation of each unit reduces unnecessary intermediate links, reduces the number of components, reduces heat generation and signal loss, and improves the stability of the circuit.
