Webb29 sep. 2024 · An active self-interference (SI) cancellation technique for SAW-less receiver linearity improvement is proposed. The active canceler combines programmable gain and phase in a single stage and is co-designed with a highly-linear LNA, achieving low noise and low power. A cross-modulation mechanism of the SI canceler is identified and strongly … WebbWhen measuring intermodulation products with a spectrum analyzer a similar situation as with cascaded active devices can occur. As a spectrum analyzer also includes non-linear devices like the input mixer or a pre-amplifier, it generates its own intermodulation products, which might have a similar amplitude as the IM products generated by the DUT.
