WEMA8: Simulating Receiver Degradation Due to an Adjacent Transmit Signal

Abstract
Receiver performances (such as error vector magnitude) are degraded by nearby transmitters. This degradation is affected by noise, filtering, amplifier distortion, power levels, transmitter-to-receiver frequency spacing and other factors. While measurement of this phenomenon is straightforward in a lab, this is often too late for design changes. Ideally, this should be investigated during the design phase. Typical simulation techniques usually make this analysis slow and difficult. This presentation shows ways to simulate such degradation using Keysight ADS in a straightforward, fast approach that designers can use during their design process and not just as a final validation.
