Embodiment Construction

[0025] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments described in the present invention are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by persons of ordinary skill in the art without making creative efforts all fall within the protection scope of the present invention.

[0026] The invention provides a balanced frequency doubler with planar structure, which is composed of 15 microstrip line networks interconnected in sequence and two Schottky diodes. Among them, the microstrip line network can be divided into three sub-networks according to their functions, namely multiplexer network A, branch line coupler B and phase-shifting network C.

[0027] Among them, the multiplexer network consists of microstrip short line 1, first microstrip line 2, second microstrip line 3, third mi...

Abstract

The invention discloses a planar balanced frequency doubler, which comprises a micro-strip line network and two diodes. The micro-strip line network is composed of a multiplexer network, a branch linecoupler and a phase shift network. The two diodes are a first diode and a second diode respectively. The traditional branch line coupler is improved into a balun needed to complete balanced frequencydoubling. Therefore, a planar balanced frequency doubler which can be used in the terahertz band is realized, the size and weight of the frequency doubler can be greatly reduced, and the frequency doubler can be directly integrated with other planar circuits.

Description

technical field [0001] The invention belongs to the technical field of communication, radar and other electronic devices, and in particular relates to a planar balanced frequency doubler applied to microwave and terahertz frequency bands. Background technique [0002] The frequency multiplier is a key component of the frequency source in electronic systems such as modern communication and radar. It multiplies the lower frequency phase-locked signal source to a higher frequency band to drive the up-conversion or down-conversion mixer. In the terahertz band, the frequency doubler is even directly used to directly multiply the frequency of the microwave or millimeter wave signal and transmit it through the antenna. [0003] Frequency multipliers can generally be divided into two types: active frequency multipliers and passive frequency multipliers. Active frequency multipliers can provide frequency multiplication gain and can usually obtain relatively large output power; passiv...
