Hybrid Couplers
3 dB, 90
Description
The 1F1305-3 is a low profile 3dB hybrid coupler in an easy to use surface
mount package specifically designed for the PCS frequencies. The
1F1305-3 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.
