The design, fabrication and experimental evaluation of a Ku-Band 3 dB Wilkinson power divider on high resistivity silicon (HRS) are presented in this paper. The measured insertion for the powder divider is 3.5 dB and isolation between port 2 and 3 is 12 dB respectively. CPW lines were fabricated on two different silicon substrates (HRS, and CMOS grade silicon) and it is shown that the loss characteristics for a 50Ω CPW patterned on the surface-stabilized HRS is only 0.16 dB at 15GHz. In contrast, the insertion loss for CPW line on CMOS grade silicon is 8.3 dB at 15 GHz. Thus, the low insertion loss could be achieved by stabilizing the surface of HRS with a thin polysilicon layer.
