Abstract

The invention discloses a novel LTCC structure based ultra wide band balun. The LTCC structure based ultra wide band balun includes a ceramic glass substrate provided with an input port Pin, an inputconnection lead Lin, an output Pout1, an output port Pout2, a grounding layer GND1, a grounding layer GND 2, a transmission wire W1 and a transmission wire W2. The transmission wire W1 and the transmission wire W2 are arranged above the grounding layer GND1. A first groove C1, a second groove C2, a third groove C3 , a fourth groove C4 and a fifth groove C5 are formed in the grounding layer GND1 through itching. The fifth groove C5 is disposed below the transmission wire W1. The first groove C1 is disposed below the transmission wire W2. The third groove C3 is connected between a connection post H and the input port Pin. One end of the second groove C2 is connected with the first groove C1 and the other end of the second groove C2 is connected with the third groove C3. One end of the fourthgroove C4 is connected with the fifth groove C5 while the other end of the fourth groove C4 is connected with the third groove C3. The lower end of the wiring post is connected with the grounding layer GND1. The novel LTCC structure based ultra wide band balun provided by the invention is low in medium loss, high in Q value, high in packaging density, short in production cycle and low in production cost.

Description

technical field [0001] The invention relates to a microwave signal transmission device, in particular to an ultra-wideband balun based on a novel LTCC structure. Background technique [0002] With the continuous upgrading of microwave communication technology, microwave devices are developing rapidly in the direction of miniaturization and broadband. As a balanced and unbalanced converter, a balun is widely used in microwave systems, such as antennas, mixers, frequency multipliers, etc., and is an important component in microwave systems. Essentially, the function of the balun is to realize the conversion between the single-ended signal and the differential signal. The balun is a three-port passive device. The main performance indicators include insertion loss, return loss, operating bandwidth, differential performance, etc. However, the existing balun devices mainly have defects such as high dielectric loss, low Q value, low packaging density, weak impact resistance, narr...
