ST Microelectronics has extended its range of single-chip antenna semiconductors designed for radio frequency circuit design.

The MLPF-NRG-01D3 for BlueNRG-LPS and MLPF-WB-02D3 system-on-chips (SoCs) for the STM32WB microcontroller integrate filtering and impedance-matching network used in RF output power and receiver sensitivity with an external antenna.

Each device has 50 Ω nominal impedance on the antenna side and features a 2.4 GHz low-pass filter to ease compliance with worldwide radio regulations including FCC, ETSI and ARIB specifications. The circuit elements are fabricated on a glass substrate and leverage ST’s integrated passive device (IPD) technology that helps accelerate time to market, reduce bill of material costs and miniaturize circuit dimensions.

The two BlueNRG SoCs and the ST microcontrollers contain ST’s energy efficient 2.4 GHz radio IP and come with royalty free protocol stacks and dedicated software tools.

These help to design wireless products without having extensive RF-design skills. Other on-chip features include:

  • Memory
  • Peripherals
  • Communication interfaces
  • Power regulation
  • Encryption
  • Memory protection
  • Public key acceleration (PKA)

Additionally, the SoCs can be used in standalone or network processor applications to support Bluetooth Low Energy and includes point-to-point and mesh communications, advertising extension and direction finding.
