Harmonic subharmonic
WebFigure 2 shows the basic architecture of a subharmonic mixer. The mixer consists of an anti-parallel diode pair, a band-pass fi lter for the RF and LO signal, and a low-pass fi lter at the IF output. What is essential in a subharmonic mixer is that the diodes are anti-parallel. Many subharmonic mixers are merely a balanced mixer WebJan 23, 2024 · The idea of a subharmonic function was expounded in essence by H. Poincaré in the balayage method. Subharmonic functions are also found in the work of F. Hartogs [1] on the theory of analytic functions of several complex variables; the systematic study of subharmonic functions began with the work of F. Riesz .
