Embodiment Construction

[0015] The circuit structure of the present invention will be further described in detail below in conjunction with the accompanying drawings. In order to illustrate the effect of the present invention, a 0.5um InP HBT process is used for design tape-out verification.

[0016] Such as figure 1 As shown, a low-power broadband frequency doubler circuit includes a push-push structure, an input balun, and two matching networks;

[0017] The first HBT tube (T1) and the second HBT tube (T2) form a push-push structure, wherein the collector of the first HBT tube (T1) is connected to the collector of the second HBT tube (T2) as the output terminal (Vout ). The emitter of the first HBT tube (T1) is connected to the emitter of the second HBT tube (T2), and then grounded. The base of the first HBT transistor (T1) is connected to the non-inverting output terminal (B2P) of the balun secondary, and the base of the second HBT transistor (T2) is connected to the inverting output terminal (...

Abstract

The invention relates to a low-power consumption broadband frequency doubler circuit. An existing frequency source has low frequency, so that the frequency doubler circuit is limited to use in the radio frequency communication system. A high-frequency frequency source is realized by cascading a voltage controlled oscillator with the frequency doubler. The low-power consumption broadband frequencydoubler circuit comprises a push-push structure, an input Balun, and two matching networks, wherein the push-push structure consists of two HBT triodes, the input Balun is realized by coupling two layers of metal up and down, and the two matching networks comprise an input matching network and an output matching network. The frequency doubler circuit works in a broader frequency range and consumesless power.

Description

technical field [0001] The invention belongs to the technical field of microelectronics, and relates to a low power consumption broadband frequency doubler circuit. Background technique [0002] In recent years, with the rapid development of millimeter-wave wireless communication systems, the application of millimeter-wave frequency sources in imaging, medical, military and other fields has become more and more popular, and the application frequency band has become higher and higher, and the demand for millimeter-wave signal sources has also increased. more urgent. However, the directly obtained high-frequency frequency source cannot meet the requirements of the communication system in terms of frequency stability and phase noise, so it is necessary to design a broadband frequency multiplier to realize the high-frequency frequency source to meet the requirements of the communication system. As the most basic building block in the high-frequency frequency source, the frequen...
