Description
The DC0350M20 is a low profile, high performance 20dB directional
coupler. It is designed for DCS & PCS 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 20 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.
