Power Dividers
In-Phase, 2-Way
Description
The 4A1305 is a low profile 2 way Wilkinson power divider in an easy to use
surface mount package designed for DCS, PCS, ISM and wireless LAN
applications. The 4A1305 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.
