Integrated transmission-line include micro-strip, strip line, etc..The integrated transmission-line of different length Width x Height characteristic can be equivalent
The distributed constant of different size of characteristic impedance realizes balanced device using these equivalent characteristic impedance characteristics.It is a little integrated
Transmission line advantage is apparent：Frequency is higher, and volume can be small, and stability is good, easy to process etc..Shortcoming is：Frequency will height.It is (general
More than 1GHz or so)
