Performance of 2–3.6 GHz Five-Port/Three-Phase Demodulators with Baseband Analog Regeneration Circuit in Direct-Conversion Receivers

Figure 8

Measured IMD2 products suppression performance versus adjacent channel power 𝑃_adj of two interfering signals around 2.8 GHz for FPD and TPD and at the outputs of the 𝐼/𝑄 regeneration circuit (𝑃_LO=5 dBm and 𝑃_RF=−35 dBm) connected to both architectures.
