STMicroelectronics has expanded its line 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 necessary for the best RF output power and receiver sensitivity with an external antenna. Each has a nominal impedance of 50Ω on the antenna side.
The chip-scale package has a tiny footprint, 0.4mm collision pitch, and a profile of just 630µm after reflow soldering. Also featuring a 2.4 GHz low-pass filter, ST's new antenna matching ICs facilitate compliance with worldwide radio regulations, including FCC, ETSI and ARIB specifications.
Circuit elements are manufactured on a glass substrate leveraging ST's integrated passive device (IPD) technology, which minimizes insertion losses and outperforms circuits built with discrete components. Integration into the same matrix also ensures consistent component parameters for superior final product quality.
Additionally, ST IPDs help accelerate time to market, reduce bill of materials costs, and miniaturize circuit dimensions.
The BlueNRG-LP and BlueNRG-LPS and STM32WB1x and STM32WB5x SoCs contain ST's energy-efficient 2.4 GHz radio IP and come with royalty-free protocol stacks and dedicated software tools. They help developers quickly design next-generation wireless products with ease, even without extensive RF design skills. Both provide on-chip capabilities such as memory, peripherals, communications interfaces, power regulation, and advanced hardware security including encryption, memory protection, and public key acceleration (PKA).
BlueNRG-LPx SoCs can be used in standalone processor or network applications and support Bluetooth® Low Energy 5.3 features, including peer-to-peer and mesh communications, advertising extensions, and direction finding.
The MLPF-NRG-01D3 IPD is compatible with all variants comprising BLUENRG-3x5Vx, BLUENRG-3x5Ax and BLUENRG-332xx in UFQFPN and WLCSP packages.
