Sliding Matched Terminations RF Microwave High Frequency Radio Loads

Kuyimitsa kwa RF ndi mtundu wa chigawo cholondola chowongolera ma vector network analyzer, omwe amakhala makamaka ndi mizere ya mpweya ndi cylindrical ferrite mkati.

The khalidwe impedance wa mzere mpweya anatsimikiza ndi awiri a kondakitala wamkati ndi awiri m'mimba mwake wa kondakitala akunja. Kuyimitsa nthawi zonse kumakhala ndi cholumikizira chamkati cholumikizidwa ndi chinthu chokhala ndi zokutira zopinga, ndipo pali mabowo owongolera pakati pa zokutira kuti akwaniritse mtengo wopingasa wofananira wothetsa. Mzere wa mpweya wa kuyimitsidwa kwa ma microwave umapangitsa kuti mawonekedwe ake akhale olondola kuposa kuyimitsa wamba.

Ndodo za maginito za Ferrite zimatha kutenga mphamvu zambiri zamaginito. Tikamatsitsa maginito a ferrite panthawi yoyeserera, kutalika kwake, chiwonetsero champhamvu, ndi gawo la mzere wa mpweya zonse zimasintha.

Pakutsetsereka kwa ferrite maginito ndodo, impedance ndi kubwerera kutayika kumatha kukonzedwa kuti zitsimikizire kulondola kwa ma calibration pama frequency apamwamba. Pakusuntha malo otsiliza kuti asinthe gawo lowonetserako koyezetsa koyezetsa, zonyamula mawayilesi zimatha kusiyanitsa cholakwika choyezera chomaliza mudongosolo kapena muyeso, ndipo amagwiritsidwa ntchito kwambiri pakuwongolera molondola kwa ma analyzer a netiweki vekitala. Chifukwa cha kuthekera kwake kosintha kwa mawonekedwe, zoyimitsa zotsetsereka zimagwira bwino ntchito pama frequency apamwamba.
