Directional Couplers
10 dB
Description
The 1W1304-10 is a low profile 10dB directional coupler in an easy to use
surface mount package covering the AMPS and GSM bands. The
1W1304-10 is ideal for power and frequency detection as well as power
injection and can be used in most high power designs. The 1W1304-10
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.
