measurement of residual phase noise of amplifiers at 80 ghz using interferometric measurement technique -开心体育

this paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for example for automotive radar sensors at 80 ghz using the interferometric measurement approach in combination with a phase noise and vco tester r&s fswp.

the setup provides a way to characterize the additive/residual phase noise of amplifiers down to -150 dbc/hz at 100 khz offset even in the microwave range at 80 ghz.
