Abstract :
This paper presents the design, fabrication, and electrical/thermal characterization of a reduced size broadband transformer balun. The balun is designed for operation in the range of 950MHz to 2.15GHz to be used in direct broadcasting satellite (DBS) front end modules. The balun is fabricated on low-loss organic laminated substrate and measures 2mmtimes1.6mm with a thickness of 0.5mm. Measurement of more than 1500 baluns, in a 75Omega system provides amplitude imbalance of less than plusmn0.5dB, phase imbalance of less than 5deg, return loss of better than 10dB, and insertion loss of better than 1.2dB
