A packaged 86–98 GHz CMOS transmitter for FMCW radar applications with 30 dBm of EIRP

In this paper a packaged X-band to W-band x9 active multiplying chain in CMOS 65 nm technology is presented. The integrated circuit was packaged and connectorized to allow FMCW Radar system operation. Wire bonds and a microstrip-to-waveguide transition were used at the output. On-chip probing showed a maximum output power of +9.7 dBm, a 3 dB bandwidth of 13% (86-98 GHz) while consuming 280 mW of DC power. An EIRP of +29.8 dBm was measured at 92 GHz by connecting a WR-10 pyramidal horn antenna to the WR-10 package output. The generic package can be employed to any circuit with an output signal from 67 to 110 GHz introducing an average 3.5 dB insertion loss in the package RF path.
