Study and Design of a 140 GHz Power Divider
摘要
A Marchand balun type power divider, using two output ports for the 135–145 GHz frequency band, is presented in this article. It allows the power supplied to the input port to be evenly distributed between the two outputs, offering better performance at frequencies above 100 GHz. Agilent's advanced design software (ADS) was used to design a two-way output balun with a 180° phase difference and identical amplitude. The balun has an insertion loss of − 3.04 dB, while the return loss and port isolation levels are less than − 18 dB and − 20 dB, respectively. It occupies an area of 500.68 µm × 811.95 µm.
