Description
The DC0900A20 is a low profile, high performance 20dB directional
coupler. It is designed for AMPS applications. This component is suitable
for feed-forward amplifier and signal sampling circuits where low insertion
loss, high directivity is required. It can be used in power applications up to
150 Watts.
Parts have been subjected to rigorous qualification testing and they are
using materials with coefficients fo thermal expansion(CTE) compatible
with common substrates such as FR4, G-10, RF-35, RO4350B and
polyimide.
