High-power high-linearity SiGe based E-BAND transceiver chipset for broadband communication

摘要

Fully integrated chipset at E-band frequencies in a superhetrodyne architecture covering the lower 71–76GHz and upper 81–86GHz bands were designed and fabricated in 0.13µm SiGe technology. The receiver chips include an image-reject low-noise amplifier (LNA), RF-to-IF mixer, variable gain IF amplifier, quadrature IF-to-baseband de-modulators, tunable baseband filter, phase-locked loop (PLL), and frequency multiplier by four (quadrupler). The receiver chips achieve maximum gain of 65dB, 6dB noise figure, better than −10 dBm IIP3, with more than 65 dB dynamic range, and consumes 600 mW. The transmitter chips include a power amplifier, image-reject driver, IF-to-RF up-converting mixer, variable gain IF amplifier, quadrature baseband-to-IF modulator, PLL, and frequency quadrupler. It achieves output power at P1dB of 17.5 to 18.5 dBm, Psat of 20.5 to 21.5 dBm, an analog controlled dynamic range of 30 dB and consumes 1.75 W.
