Directional Couplers
6 dB
Description
The 1D1304-6 is a low profile 6dB directional coupler in an easy to use
surface mount package covering the AMPS and GSM bands. The
1D1304-6 is ideal for inline split/combine1 amplifiers and for 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.
