Directional Couplers
10 dB
Description
The 1W1305-10 is a low profile 10dB directional coupler in an easy to use
surface mount package covering the DCS and PCS bands. The 1W1305-
10 is ideal for power and frequency detection as well as power injection
and can be used in most high power designs. The 1W1305-10 has
modified RF pads which can handle higher peak power levels than the
standard Xinger designs. Also, the new RF pad improves manufacturing
reliability and minimizes the risk of failures due to misalignment from pick
and place equipment. 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.
