SU1682942A2 - Transistor holder in devices for measuring electrical parameters - Google Patents

Abstract

The invention relates to a radio metering technique and can be used in devices for measuring electrical parameters of transistors. The purpose of the invention is the expansion of operational capabilities and ease of operation. This is achieved by the fact that the holder of trachiotors contains two coaxial-strip transitions 1, two segments of strip line 2, common base 3, pedestal 4, transistor (for example, ZP602) 5, cover 6, directional couplers 7, detectors 8, polycore boards 9 with matched loads 10, contact node 11. P - I - p-diodes 12, bias circuit 13, p - I - p-diodes 12 are included in the matched shoulders of directional couplers 7, one of whose outputs is loaded on matched load 10 and other outputs - to detectors 8. Offset circuits of p-i-p-diodes 12 on chayut in SEB blocking capacitance and inductance. The transistor holder provides the combination of the functions of the holder and the measuring sensors and eliminates the need for its calibration as an independent measuring device. The transistor holder ensures measurement accuracy of not less than 5% modulo and 10 ° amp; in phase. 1 h. the item of f-ly, 4 ill. (L with
