W-band high bit passive phase shifter for automotive radar applications in BiCMOS
This paper presents a 65-85 GHz 5-bit passive phase shifter at the desired frequency of 77 GHz, using CMOS switches available in the 0.13 μm SiGe BiCMOS process. The phase shifter is based on a low-pass π-network and CMOS passive transistors. The RMS phase error, the insertion loss and the VSWR is l...

Summary: | This paper presents a 65-85 GHz 5-bit passive phase shifter at the desired frequency of 77 GHz, using CMOS switches available in the 0.13 μm SiGe BiCMOS process. The phase shifter is based on a low-pass π-network and CMOS passive transistors. The RMS phase error, the insertion loss and the VSWR is less than 3.5°, -20 dB and 2 at 77 GHz respectively, so it is possible to precede this design with a high gain LNA without loss of system linearity or input power handling and it is convenient for afterwards signal processing. |
