0.1-5.0GHz DP4T Antenna Switch Module



Low insertion loss is exhibited in every path in FX5724, from the antenna port to any of the RF port, with high isolation between both opposite and adjacent paths. In addition, the FX5724 also achieves excellent linearity performance.


The FX5724 is a DP4T (double-pole four-throw) antenna switch module, designed for multimode broadband cellular applications, supporting GSM, WCDMA, LTE and 5G NR from 100MHz to 5.0GHz. The RF performance is optimized with low insertion loss and low harmonics to guarantee the stringent requirements of all LTE standards.



No external DC blocking capacitors are required as long as no DC voltage is applied on any RF path.



The FX5724 integrates a DP4T switch and a RFFE serial controller on a single SOI chip. Equipped with 4 symmetrical transmit/receive ports for GSM/WCDMA/LTE/5G NR, the FX5724 is providing the most versatile combinations of operation in different modes.



The FX5724 is encapsulated in a compact 2mm x 2mm LGA package, with low profile of 0.51mm. This product is RoHS-compliant and halogen free.



The FX5724 is rated to Moisture Sensitivity Level 3(MSL3) at 260°C per JEDEC J-STD-020.
