Description
The 1A1306-20 is a low profile 20dB directional coupler in an easy to use
surface mount package for PCS, ISM and wireless LAN applications. The
1A1306-20 is ideal for frequency detection and VSWR monitoring and can
be used in most high power designs. They have been subjected to
rigorous qualification testing and units are 100% tested. Parts are
manufactured using materials with x and y thermal expansion coefficients
compatible with common substrates such as FR4, G-10 and polyamide.
