Leave the wire long enough to get a good grip and wear gloves if necessary. Twist the twisted part together tighter.
웹2015년 7월 23일 · 2015-07-23. The balun (a contraction of balanced-unbalanced) is a two-port component placed between a source and load when a differential, balanced RF functional block must connect to a single-ended, ground-referenced one. Although it is often “glossed over” in RF discussions because it does not add obvious value to the RF signal chain ... 웹미디움 파워 발룬. 기존에 저희가 만들던 하이 파워 발룬 (BASICOMM Balun) 에 비해 가볍게 만들었고, 주로 와이어 안테나에 사용하기 편한 형태로 개발 했습니다. 작고 가벼워졌다고 말씀드리고 있지만 실제로 성능을 위해 고려한 여러 부분 때문에 일반적으로 자주 ...
