Description
The DC0350M20 is a low profile, high performance 20dB directional couple r . 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 W atts. Parts have been subjected to rigorous qualification testing and they are using materials with coe f ficients fo thermal expansion(CTE) compatible with common substrates such as FR4, G-10, RF-35, RO4350B and polyimide. Note: 1. All above test data resulting from specify demo board. 2. Insertion loss has removed the thru board loss.
