Infineon BGS12PL6E6327 SP6T RF Switch: Key Features and Applications

The Infineon BGS12PL6E6327 is a high-performance single-pole six-throw (SP6T) RF switch designed to meet the demanding requirements of modern wireless communication systems. Fabricated using Infineon’s advanced silicon-on-insulator (SOI) technology, this component offers exceptional RF performance, low power consumption, and high integration, making it a preferred choice for a wide range of applications from consumer electronics to infrastructure equipment.

Key Features

One of the standout attributes of the BGS12PL6E6327 is its broad frequency coverage from 100 MHz to 6 GHz, encompassing most cellular and connectivity bands, including 5G sub-6 GHz, LTE, WCDMA, GSM, WiFi 6/6E, Bluetooth, and GPS. This wideband operation allows designers to use a single switch across multiple protocols and frequency plans, simplifying board design and reducing bill-of-materials complexity.

The switch exhibits low insertion loss, typically as low as 0.5 dB at 2 GHz, which is critical for preserving signal integrity and maximizing system sensitivity and output power. It also provides high isolation, exceeding 35 dB at 2 GHz, effectively minimizing unwanted signal leakage between ports and preventing interference between adjacent paths.

A significant advantage is its exceptional power handling capability, supporting up to 38 dBm of input power at 3.8 V. This robust performance ensures reliable operation in high-power transmit paths without risk of damage or performance degradation. Furthermore, the device integrates a negative voltage generator, allowing it to be controlled with a standard positive logic voltage (1.8 V) while internally generating the negative gate bias required for the SOI switches. This eliminates the need for an external negative voltage supply, simplifying system design and saving space.

The BGS12PL6E6327 is also designed for ease of use, featuring a serial peripheral interface (SPI) for control. This digital interface enables compact and simple control logic, reducing the number of GPIOs required from the baseband or RF controller.

Primary Applications

Thanks to its versatile performance, the switch is ideal for a multitude of applications:

Smartphones and Mobile Devices: It is perfectly suited for antenna tuning and aperture tuning modules, where it dynamically switches between multiple antennas or matching networks to optimize signal reception and data throughput across diverse frequency bands.

5G Infrastructure: In massive MIMO (Multiple Input Multiple Output) systems and active antenna systems (AAS), this SP6T switch can be used for beamforming networks, routing signals to different antenna elements.

IoT and CPE Equipment: It is used in customer premises equipment (CPE) and IoT modules for band selection and signal routing between primary, diversity, and GNSS antennas, ensuring reliable connectivity.

Test and Measurement: Its high linearity and wide frequency range make it an excellent choice for automated test equipment (ATE) and RF test fixtures where precise signal routing is required.

ICGOOODFIND: The Infineon BGS12PL6E6327 stands out as a highly integrated and robust SP6T RF switch. Its combination of wide bandwidth, low insertion loss, high power handling, and the integrated negative voltage generator makes it an exceptionally flexible and reliable solution for next-generation wireless designs, from mobile handsets to complex infrastructure systems.
