Infineon – BGS1xPN10 Family for Mobile Cellular Rx/Tx Applications (High Linearity/RF Switches, SPDT, SP3T and SP4T)


Infineon Logo       NPI_LOGO
The BGS12PN10 single pole dual throw (SPDT), the BGS13PN10 single pole triple throw (SP3T) and the BGS14PN10 single pole quad throw (SP4T) are high linearity, high power RF switches optimized for mobile phone applications up to 6.0GHz.

These single supply chips integrate on-chip CMOS logic driven by a simple, CMOS or TTL compatible control input signal. Unlike GaAs technology, the 0.1dB compression point exceeds the switch maximum input power level, resulting in linear performance at all signal levels, and external DC blocking capacitors at the RF ports are only required if DC voltage is applied externally.

The BGS12PN10, BGS13PN10 and BGS14PN10 enable critical band combinations for UL (B1 + B3), (B2 + B4), DL-CA (B4 + B12) and SV-LTE (B5 + B13). These devices handle very high transmitting signal levels of up to 40dBm, while at the same time exhibiting low losses to conserve battery power. Ultra high linearity devices have a significant impact on system sensitivity. For instance, 3dBm more linearity in the whole RF-front-end leads to 6dB better signal-to-noise ratio. Hence, data rate speed is improved by up to 40% allowing a step e.g. from 20Mbps (QAM16 4/5) to 33Mbps (QAM64 4/5). The BGS12PN10, BGS13PN10 and BGS14PN10 stand for best in class ISO and IL performance across all frequencies.
