Study and analysis of a QFN packaged 8-bit Phase shifter design using 65-nm CMOS technology

8- bit digital phase shifter is design in 65nm CMOS technology and is packaged using QFN. This work is aimed to study the effects of the wire bonds without any compensation or matching work being done to the chip. It is observed that the insertion loss variation and return losses are affected much but the phase performances remains more or less same as the design.
