摘要： A measuring apparatus that measures a characteristic of a device under measurement is provided. The measuring apparatus includes: a signal generating section that outputs a forward signal to the device under measurement through a device side terminal; a directional coupler that outputs a backward split signal obtained by splitting a part of a backward signal inputted from the device under measurement through the device side terminal; a backward mixer that outputs a backward detection signal obtained by multiplying a local signal having a predetermined frequency by the backward split signal; and an analysis section that analyzes a characteristic of the device under measurement based on the backward detection signal. The directional coupler is included in a multilayer substrate, and the backward mixer is included in a chip provided on a surface of the multilayer substrate.

摘要： The frequency characteristic of a conversion loss is kept generally constant during conversion of a high frequency received signal into an intermediate frequency signal. There is provided a frequency converter including a balanced balun (10) which branches a locally oscillated signal (Lo) into two signals which have the same amplitude and are different from each other in phase by 180 degrees, low-pass filters (12a, 12b) through which the two signals pass, and antiparallel diode pairs (16a, 16b) which respectively mix outputs from the low-pass filters (12a, 12b) with a high frequency received signal (RF) to produce an intermediate frequency signal (IF) The low-pass filters (12a, 12b) exhibit generally constant impedances in the frequency band of the high frequency received signal (RF). Accordingly, the impedances of the anti-parallel diode pairs (16a, 16b) as viewed from an anti-parallel diode connection point (17) are generally constant in the frequency band of the high frequency received signal (RF), with the result that the frequency characteristic of the conversion loss can be kept generally constant.

摘要： A single balanced mixer has a high degree of isolation between an IF signal and an RF signal and a high conversion efficiency. The single balanced mixer includes means for producing two local signals of same amplitude and opposite phase, a pair of mixing elements each receiving a corresponding one of the two local signals, a pair of strip lines for transmitting the input RF signal to the mixing elements. One end of each of the strip lines is connected to one another at a point where the RF signal is supplied and other end of each of the strip lines is connected to the corresponding mixing element. A length of each of the strip lines is one fourth of a wave length of the IF signal.
