This paper presents a distributed model of a lumped-element quadrature coupler that accounts for the distributed nature of parasitic elements. The required capacitors in the constitution of lumpedelement quadrature couplers can be properly considered using the proposed distributed model. An integrated low loss lumped-element quadrature coupler is implemented using the proposed model. The modeled responses are compared with the corresponding measured responses; they exhibit good agreement. The measured insertion loss for both direct and coupled ports is 3.23 dB at 5.5 GHz. The variation in the insertion loss is ± 0.3 dB with a phase imbalance of less than 0.95° across a 760-MHz bandwidth.
