Frequency Quadruplers for a 77GHz Subharmonically Pumped Automotive Radar Transceiver in SiGe

Description

Frequency quadruplers for an integrated 77GHz subharmonically pumped automotive radar transceiver in SiGe are presented. The fully differential circuits are integrated in a 200GHz SiGe:C production technology and operate at a supply voltage of 3.3V. Two different multiplier concepts are introduced and evaluated. The individual multipliers are combined with a radar transceiver circuit and the receive mixer performance is demonstrated. The 77GHz radar transceiver is pumped with a 19GHz LO signal, which is quadrupled and amplified to drive a power amplifier and the switching transistors of a Gilbert-type mixer.
