11305-10 is a low-profile 10dB directional coupler, installed in an easy-to-use surface-mount package, covering the frequency range of 1.0 to 2.0 GHz. 11305-10 is an ideal choice for power and frequency detection as well as power injection, and can be used in most high-power designs. The parts have undergone strict qualification tests, and the 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).
