摘要: A frequency discriminator (1) stabilizes a voltage controlled oscillator (5), particularly one operating at microwave frequencies. single dielectric resonator (2), typically positioned within housing (8), is excited by an r.f. input (30). The (2) generates in response to the excitation first and second orthogonal modes of electromagnetic energy slightly different two are converted d.c. output signals (39, 40) opposite polarity substantially same magnitude, e.g., diodes (35, 36). Frequency offsets obtained tuning screws (43, 44) and/or changing amount path characterizing vector corresponding mode being frequency-offset.
