RF SAWs simplify RF design in advanced LTE and WCDMA networks

April 05, 2012 // By Jean-Pierre Joosting
TriQuint Semiconductor has released three RF SAW filters that can cost-effectively improve performance in 3G / 4G network infrastructure and legacy system applications.

TriQuint is focused on bringing performance innovation to the essential building blocks of global networks. These networks are fraught with mobile data traffic demand and continued double-digit growth is expected. In the first five weeks of 2016 the volume of mobile data traffic is expected to surpass the total data that wireless networks carried in all of 2011. While mobile data traffic volume increases, so does the need for highly-efficient networks that can support the broadband designs typical of advanced WCDMA, LTE, TD-SCDMA and multimode systems.

The 856934, for Band 3 at 1842.5 MHz, provides 75 MHz bandwidth, a maximum 4.2 dB insertion loss and attenuation of 20 dB at 1785 MHz. TriQuint's 857019, for an extended Band 5 at 835 MHz, offers 30 MHz bandwidth, a maximum 3.0 dB insertion loss and attenuation of 20 dB at 869 MHz. The 856977, for Bands 13 and 14 at 787.5 MHz, delivers 22 MHz bandwidth, a maximum 2.75 dB insertion loss and attenuation of 40 dB at 843 MHz.
