abstract = "In this work, on-chip single-to-balanced bandpass filters with wide upper stopband are proposed. The proposed filter integrate the functions of bandpass filter and balun using a simple multicoupled line structure along with loaded capacitors. The use of inductor is avoided such that they can achieve very compact size when implemented on chip. They can be designed according to the desired bandpass response and reference impedance. Specifically, two single-to-balanced filters of 2nd-and 3rd-order bandpass response are demonstrated using the GaAs pHEMT process. Their chip sizes are 1×1 mm2 and 1.5×1 mm2 for a center frequency of 5.5 GHz and a bandwidth of about 18%. The corresponding electrical sizes are only about 0.036λg × 0.045λg and 0.062λg × 0.043λg, respectively. Good balanced performances are observed with common-mode rejection ratio better than 29 dB. Notably, very wide upper stopbands up to the highest measurement frequency of 67 GHz are also achieved.",
