Directional Couplers
30 dB
Description
The 1A1305-30 is a low profile 30dB directional coupler in an easy to use
surface mount package covering the DCS and PCS bandwidth. The
1A1305-30 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.
