Item Open Access Compact and wideband CPW wilkinson power dividers for GaN MMIC applications(IEEE, 2018) Sutbas, Batuhan; Özbay, Ekmel; Atalar, AbdullahThis paper presents two types of modified CPW Wilkinson power dividers at X-band using GaN MMIC technology on a SiC substrate. Lumped element equivalents of the transmission line arms are used and they are capacitively loaded to achieve a reduced circuit size of lambda/14timeslambda/8. A symmetrical series RLC circuit in the isolation network is used to compensate for the bandwidth degradation after circuit miniaturization maintaining a fractional bandwidth of 29 % for input/output return losses and isolation better than 20 dB with an extra insertion loss less than 0.35 dB.
