Rev. A
Power Dividers
In-Phase, 3-Way
Description
The 4A3305 is a low profile 3 way Wilkinson power divider in an easy to use
surface mount package designed for DCS and PCS applications. The
4A3305 is ideal for low power, in phase divider/combiner applications.
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.
