Hybrid Couplers
3 dB, 90
Description
The 1W1305-3 is a low profile 3dB hybrid coupler in an easy to use surface
mount package covering DCS, PCS, W-CDMA, UMTS and other 3G
applications. The 1W1305-3 is ideal for balanced amplifiers and signal
distribution and can be used in most high power designs. The 1W1305-3
has modified RF pads that 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.
