Hybrid Couplers
3 dB, 90°
Description
The 2K1305-3 is a low profile, high power 3dB hybrid coupler in an easy to
use surface mount package covering the Japanese PDC band. The
2K1305-3 is ideal for balanced amplifiers and signal combining and can be
used in most high power designs. Parts have been subjected to rigorous
qualification testing and units are 100% tested. They are manufactured
using materials with x and y thermal expansion coefficients compatible with
common substrates such as FR4, G-10 and polyamide.
