The Signal and Noise Analysis of Direct Conversion EHM Transceivers
نویسندگان
چکیده مقاله:
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 analysis of the signal and noise has been presented.

Correction of nonlinear and frequency dependent distortion in a 3.3 GHz, 16-element digital phased array is demonstrated using the memory polynomial model from [4] and a weighted least-squares approach. Practical results are given, showing that a single solution of the system can correct distortion from data sets across the whole operational bandwidth of the array. Subsequent analysis of perfor...
