Ku-band compact Wilkinson power divider based on multi-tap inductor technique in 65-nm CMOS

Abstract

This paper presents a Ku-band compact Wilkinson power divider (WPD). The proposed WPD is realized by a multi-tap inductor with shunt capacitors to achieve low insertion loss, broadband isolation while minimizing chip area. Occupying only 188 × 116 µm 2 , the proposed WPD achieves a measured insertion loss of less than 1 dB from 1 to 16 GHz. From 11 to 16 GHz, the measured isolation is better than 20 dB with input and output return losses higher than 16 and 21 dB, respectively.

A Ka-Band Balanced Four-Beam Phased-Array Receiver With Symmetrical Beam-Distribution Network in 65-nm CMOS

“…At the first stage of the network, a single-ended WPD is employed. To reduce the large area of the λ/4 transmission line (TL) in the WPD, lumped-element WPDs have been employed [21]. In this design, the λ/4 TL is implemented by a five-tap inductor to ensure compact size and broad bandwidth simultaneously.…”
