Abstract-A transformer that uses bonder-wires and printed circuit board (PCB) patterns is proposed for RF circuit applications. The proposed transformer can be constructed without any additional processes. The PCB patterns are implemented using a typical FR4 substrate and gold bonder wires are used. The self-inductance of the transformer can be controlled according to the number of unittransformers. Although the size of the transformer is larger than that of a fully-integrated transformer, the maximum available gain (MAG) is almost identical to that of other-types of transformers, which require additional cost or bulky size to obtain sufficient inductance. Additionally, we proposed a method to design the transformer with a symmetric structure for differential RF CMOS circuit applications. The transformer can applied to GHz-order RF CMOS circuits as an input and output matching component with low loss characteristics.

A compact broadband BALUN transformer is designed using the Klopfenstein taper line transformer approach to transform a 50 Ω impedance into 100 Ω. To reduce the length of the conventional BALUN, a straight microstrip (MS) line is modified as a curved MS line. The proposed compact BALUN is 56.7%-73% smaller w.r.t the straight conventional BALUN but at the cost of a 4.5%-13% reduction in the overall band. The conventional BALUN has a measured % bandwidth of 165, while the compact BALUN has a result of 159. The measured results agree with the simulated results.
