PROBE CONTAINING DIODE ASSEMBLY FOR RADIO FREQUENCY PEAK POWER DETECTION

摘要

A probe assembly for applying to a peak power meter detected radio frequency signals whose peak power is to be measured, comprising a tubular conductive member having a plurality of interconnected detachable cylindrical parts. A co-axial transmission line at one end of the tubular member receives the radio frequency signals which are applied to a disk resistor and an anode of a thermionic ceramic planar diode within the tubular member. The cathode of the diode is connected to a filter which includes a geometric capacitor. The diode detects the radio frequency signals and produces a video frequency envelope which after filtering is passed to the peak power meter.
