STMICROELECTRONICS REVEALS SINGLE-CHIP ANTENNA-MATCHING ICS WITH BLUETOOTH^® LE SOCS AND STM32 WIRELESS MICROCONTROLLERS

STMicroelectronics has extended its range of single-chip antenna-matching ICs that simplify RF-circuit design with two new devices optimized for BlueNRG-LPS system-on-chip ICs (SoCs) and STM32WB1x and STM32WB5x wireless microcontrollers.

The MLPF-NRG-01D3 for BlueNRG-LPS and MLPF-WB-02D3 for STM32WB integrate the complete filtering and impedance-matching network needed for the best RF output power and receiver sensitivity with an external antenna.

The circuit elements are fabricated on a glass substrate leveraging ST’s integrated passive device (IPD) technology, which minimizes insertion losses and outperforms circuits built with discrete components. Integration on the same die also ensures consistent component parameters for superior end-product quality.

BlueNRG-LPx SoCs can be used in standalone or network processor applications and support Bluetooth^® Low Energy 5.3 features including point-to-point and mesh communications, advertising extensions, and direction finding. The MLPF-NRG-01D3 IPD is compatible with all variants, comprising the BLUENRG-3x5Vx, BLUENRG-3x5Ax, and BLUENRG-332xx in UFQFPN and WLCSP packages.

The STM32WB5x and STM32WB1x MCUs are Bluetooth 5.3, Zigbee^® 3.0, and OpenThread certified and feature an Arm^® Cortex^®-M4 core for application processing with a Cortex-M0+ dedicated to managing the radio.

The MLPF-NRG-01D3 and MLPF-WB-02D3 single-chip antenna-matching ICs are in production now and available from $0.14 for orders of 1000 pieces.
