Features Large heat dissipation area can better maintain long term operation, and can also ensure the efficient operation of the machine. The signal of a specific frequency band pass, and block and filter the clutter with frequency lower than and higher than the signal frequency range. SMA connector has the characteristics of small size, high reliability, bandwidth, excellent performance, long life, etc. Miniaturization, light weight, high speed signal transmission, high pass frequency band reduces work difficulty and increases work efficiency. Adopts Approx. 1.6mm/0.06in thick double sided board, and the whole process of spraying tin to ensure good passing performance of large and small current.
