3 dB, 90
Description
The 1A1306-3 is a low profile 3dB hybrid coupler in an easy to use surface
mount package for PCS, ISM and wireless LAN applications. The 1A1306-
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.
