11302-20 is a low-profile 20dB directional coupler, installed in an easy-to-use surface-mount package, covering 190 to 400 MHz. 11302-20 is an ideal choice for power and frequency detection as well as voltage standing wave ratio monitoring, and can be used in most high-power designs. The parts have undergone strict qualification tests, with 100% of the units tested. They are manufactured using materials with x and y thermal expansion coefficients compatible with common substrates (such as FR4, G-10, and polyamide).
