Bath A direct conversion modulator-demodulator with even harmonic mixers with emphasis on noise analysis is presented.The circuits consist of even harmonic mixers (EHMs) realized with antiparallel diode pairs (APDPs).We evaluate the different levels of I/Q imbalances and DC offsets and use signal space concepts to analyze the bit error rate (BER) of the proposed transceiver using M-ary QAM schemes.Moreover, the simultaneous Tamper Proof Case analysis of the signal and noise has been presented.
