Original Kurzfassung:
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.
