FX5722（5G射频前端解决方案）

Description

The FX5722 is rated to Moisture Sensitivity Level 3(MSL3) at 260°C per JEDEC JSTD-020.

The FX5722 is a DPDT (Double-pole double-throw) switch designed for multimode broad

band LTE/5G NR cellular applications, supporting from 100MHz to 6.0GHz. The RF perfor

mance is optimized with low insertion loss and high linearity to guarantee the stringent 

requirements of all LTE/5G NR standards.

The FX5722 integrates a DPDT switch and a GPIO controller on a single SOI chip. Low 

insertion loss is exhibited in every TRx path in FX5722, with high isolation and low 

harmonics. In addition, the FX5722 also achieves excellent linearity performance, suitable

for LTE/5G NR applications. The internal decoder allows convenient GPIO connections 

and supports digital control signals. The SOI architecture in FX5722 removes the external

DC blocking capacitors to save the cost and PCB space.

The FX5722 is encapsulated in a compact 1.1mm x 1.5mm, 10-pin, LGA package, with 

low profile of 0.51 mm. This product is RoHS-compliant and halogen free.
