1 FX GHz DPDT Switch Module Description The FX5767 is a DPDT (Double-pole double-throw) switch module, designed for multimode broadband 3G/LTE cellular applications, supporting from 700MHz to 3.0GHz. The RF performance is optimized with low insertion loss and high linearity to guarantee the stringent requirements of all 3G/LTE standards. The FX5767 integrates a DPDT switch and a GPIO controller on a single SOI chip. Low insertion loss is exhibited in every TRx path in FX5767, with high isolation and low harmonics. In addition, the FX5767 also achieves excellent linearity performance, suitable for 3G/LTE applications. The internal decoder allows convenient GPIO connections and supports digital control signals. The SOI architecture in FX5767 removes the external DC blocking capacitors to save the cost and PCB space. The FX5767 is encapsulated in a compact 2mm x 2mm LGA package, with low profile of 0.55mm. This product is RoHS-compliant and halogen free. The FX5767 is rated to Moisture Sensitivity Level 3(MSL3) at 260 C per JEDEC J- STD-020.

6 Evaluation Board Layout Board Size 29mm x 27mm Notes for Evaluation Board 1. The copper pad on the bottom of the package should be soldered to the ground plane of the evaluation board. 2. The ground pad area should be big enough and there should be many the through vias on this ground pad, which are critical for thermal and RF performance. 3. The thickness of copper on both surface sides of the evaluation board is recommended to be 1 or 2 ounce. 4. Measurement data in this datasheet is based on an Rogers board with 1.2 mm thickness and 1 ounce copper on surface. 6
