6 dB
Description
The 1A1305-6 is a low profile 6dB directional coupler in an easy to use
surface mount package covering the DCS and PCS bands. The 1A1305-6
is ideal for inline split/combine amplifiers and for power injection 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.
