A fully integrated 77-GHz Radar Transmitter based on a Low Phase‑Noise 19.25‑GHz Fundamental VCO

Description

A 77‑GHz automotive radar transmitter is presented. The transmitter is based on a 19.25‑GHz Colpitts voltage controlled oscillator, that feeds two cascaded frequency doubler stages. In a following medium power amplifier (MPA) the signal recovers after frequency transformation. Finally a power amplifier (PA) adds 6 dB to the power level after the MPA. In addition, an emitter follower stage connected to the oscillators output drives a switchable divide‑by‑16/32 stage realized in emittercoupled‑ logic (ECL).
