DC0450E20

Description The DC0450E20 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 100 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.
