SHF POWER CONVERTER Russian patent published in 1996 - IPC

FIELD: radioelectronic industry. SUBSTANCE: 1. SHF power converter has waveguide section, one wall of which has hole, in which flat membrane of absorbing material is mounted. Membrane is connected to vibration system of mechanical oscillations generator. SHF power converter differs from others by the fact, that to increase accuracy of measurements in operational frequencies range by decreasing of mismatch error alternating component, flat membrane is made in the form of ellipsis, one of axes of which is in parallel to longitudinal axis of waveguide section. 2. SHF power converter differs from others by the fact, that to increase measurement accuracy on fixed frequency flat membrane length "l" and size of wide wall of waveguide section are chosen from condition, that l/l/λ = 0,612+(K/2), = 0.612 + (K/2), with K = 0, 1, 2, 3, ...; λ - length of operational wave; EFFECT: increase accuracy of measurements.
