Power Dividers
In-Phase, 2-Way
Description
The 4D1304 is a low profile 2 way Wilkinson power divider in an easy to
use surface mount package designed for AMPS and GSM band
applications. The 4D1304 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.
