Description
The 1A1305-5 is a low profile 5dB directional coupler in an easy to use
surface mount package covering the DCS and PCS bands. The 1A1305-5
is ideal for 3 way inline split/combine 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.
