Excellent broadband RF performance with RF switches from Infineon

Infineon offers Bulk CMOS RF Switches to support a variety of applications, such as traditional single pole multi throw switches (e.g. for general purpose switching, band/mode switching and antenna diversity applications), double pole double throw (DPDT) switches and antenna switch modules (ASM).

Highly linear band or mode switches are vital for emerging multi-mode and multi-band architectures as mobile phone radios can easily operate in 16 bands or more. Some examples of band/mode switch products from Infineon Technologies include the SPDT models BGS12SL6, BGS12PL6 and BGS12SN6, the SP3T model BGS13SL9 and the double-pole, double-throw (DPDT) models BGS22WL10 and BGS22W2L10.

Furthermore, several Infineon devices with mid-range power capability are suggested for the diversity application to increase data rates in emerging mobile phone radios.

Infineon RF switches are highly linear and provide the required isolation between transmit and receive chains, with the lowest insertion loss possible. They are typically implemented one of two ways: as discrete TSxP packaged or they can be delivered by a third-party module manufacturer which uses our chip-scale-packages (CSP).Then, the control may be done in many different ways. However, upcoming designs are moving away from traditional general purpose input/output (GPIO) to Mobile Industry Processor Interface (MIPI) RFFE interface.
