RF Micro Devices Inc. adds the RF8889A, RF1291, RF1194A and RF1196 to its portfolio of front end modules for 3G/4G switch and signal conditioning applications that are optimised to solve the complex RF requirements of 3G/4G smart phones related to high band count and harmonics.

The RF8889A and RF1291 are single-pole 10 throw (SP10T) antenna switch modules (ASMs). They claim industry-leading linearity performance and good insertion lOS for high-throw count applications. They are compatible with reference designs from Qualcomm, Intel and ST-Ericsson, targeting smart phone applications in which the coexistence requirements of multiple radio standards (GSM/WCDMA/LTE/Wi-Fi/Bluetooth) place critical importance on switch linearity and harmonic performance.

The RF1194A switch filter module (SFM) expands the functionality of the first two devices by adding GSM Rx SAW filters.

The RF1196 switch duplexer module (SDM) delivers the switch and filter capabilities of RFMD's ASMs and SFMs and expands upon their functionality by integrating a WCDMA band 1 duplexer. The RF1196 is first in a family of RFMD SDM products that significantly reduce total solution size by delivering complete front end integration of all switch and filter requirements in a single front end module.
