유통업체에서 제공한 Fairview Microwave FMBL1004에 대한 설명입니다.
100 MHz to 520 MHz Balun at 50 Ohm to 25 Ohm Rated to 100 Watts in a SMT (Surface Mount) Pack-
BALUN 100MHZ ~ 520MHZ 50 / 25OHM
The FMBL1004 is part of a family of 100 watt surface mount baluns. It converts between a 50 ohm unbalanced signal (one signal referenced to ground) and balance signals (two 50 Ohm signals referenced to each other, 25 Ohms referenced to ground). These baluns have many useful applications. For example, when matching to low impedances (like transistors), these baluns allows improved matching to applications like push-pull amplifiers with improved bandwidth, and losses while providing second harmonic cancelation.
