May 11, 2017 // By Jean-Pierre Joosting
Designed for smartphones, data cards, and MiFi® hotspots, the SKY13698-694LF from Skyworks claims to be the lowest insertion loss, high isolation antenna swap DPDT switch currently available on the market.

With industry-leading insertion loss across all cellular bands, the ultra-low loss DPDT switch maintains isolation >30 dB at 3.8 GHz, preventing signal leakage and mitigating Rx desense issues. Its wide frequency range of 0.4 to 5.9 GHz makes it the first cellular antenna swap device to support emerging, new high band applications such as LAA/LTE-U and sub-6 GHz. 

The switch delivers excellent harmonic and linearity ensures flawless RF performance and it offers robust GSM power handling capability.  It is provided in a compact Quad Flat No-Lead (QFN) 1.83- × 1.83- × 0.5-mm package and no external matching components are required.
