Directional Couplers
30 dB
Description
The 1G1304-30 is a low profile 30dB directional coupler in an easy to
use surface mount package covering the AMPS and GSM bands. The
1G1304-30 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.
