Hybrid Couplers
3 dB, 90
Description
The 1K1305-3 is a low profile 3dB hybrid coupler in an easy to use surface
mount package covering the Japanese PDC bandwidth. The 1K1305-3 is
ideal for balanced amplifiers and signal distribution 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.
