Abstract :
Frequency quadruplers for an integrated 77 GHz subharmonically pumped automotive radar transceiver in SiGe are presented. The fully differential circuits are integrated in a 200 GHz SiGe:C production technology and operate at a supply voltage of 3.3 V. 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 77 GHz radar transceiver is pumped with a 19 GHz LO signal, which is quadrupled and amplified to drive a power amplifier and the switching transistors of a Gilbert-type mixer.
