Hybrid Couplers
3 dB, 90
Description
The 11303-3 is a low profile 3dB hybrid coupler in an easy to use surface
mount package covering the NMT 450 band. The 11303-3 is ideal for
balanced amplifiers and signal distribution 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.
