Directional Couplers
10 dB
Description
The 11305-10 is a low profile 10dB directional coupler in an easy to use
surface mount package covering 1.0 to 2.0 GHz. The 11305-10 is ideal
for power and frequency detection as well as power injection and can be
used in most high power designs. 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.
