Directional Couplers
20 dB
Description
The 11302-20 is a low profile 20dB directional coupler in an easy to use
surface mount package covering 190 to 400 MHz. The 11302-20 is ideal
for power and frequency detection as well as VSWR monitoring 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.
