Guerrilla Amplifier Chosen for Impinj RFID Reader
Guerrilla RF’s GRF5509 4-watt power amplifier was selected by Impinj for use in their enterprise-grade RAIN RFID reader module reference design. This integration allows customers to quickly go to market and develop new readers built on Impinj’s E family reader ICs.
The GRF5509 is an InGaP HBT PA that can be tuned to operate over select bands within the 700 to 1000 MHz frequency range. When tuned for the RFID UHF bands of 866 MHz to 928 MHz, the PA delivers 38 dB of gain, 36 dBm of OP1dB compression, and 46 dBm of OIP3 linearity. Like other GRF amplifier cores, the GRF5509 features a flexible biasing architecture allowing customizable trade-offs between linearity and power consumption. Supply voltages can vary between 3.0 and 5.5 V.
Jim Ahne, senior vice president of marketing at Guerrilla RF, noted the pairing helps to accelerate the development of feature-rich capabilities across the market.
“The GRF5509 delivers up to 2 watts of linear power while meeting the stringent spectral mask requirements required for these reader applications. Guerrilla RF has a full suite of alternative amplifiers as well for applications that might require lower output power levels,” said Ahne.
Vikas Dhurka, senior director of product management for reader ICs at Impinj, added “accurately and reliably reading RAIN tags is critical to successful deployments. By integrating Guerrilla RF’s GRF5509 high-performance amplifier, the Impinj E family based RAIN RFID reader module reference design with Impinj Gen2X support delivers the highest possible transmit power, enhancing read range and enabling our customers to successfully read detuned tags.”
Bureau Raises $30 Million to Combat Fraud
With global fraud losses hitting $486 billion annually, Bureau recently announced $30 million in Series B fundraising. A leading risk intelligence platform, which has seen its revenue grow three times since it’s last funding round, the company arms businesses with AI to combat the rise in sophisticated fraud attacks worldwide.
The round was led by Sorenson Capital with participation from PayPal Ventures and continued support from Commerce Ventures, GMO Venture Partners, Village Global, Quona Capital, and XYZ Ventures. The funding will accelerate Bureau’s product expansion into new use-cases, and geographical expansion to several new markets worldwide to meet a significant surge in global demand.
The funding will support two key expansion initiatives: enhanced data and AI capabilities to improve decision efficiency and coverage, and geographical expansion to serve more markets globally. Bureau’s current focus has been on Asia, and this round will fuel its expansion to additional regions, enabling more businesses worldwide to access its comprehensive fraud prevention capabilities.
“As cyberfraud reaches unprecedented levels, Bureau stands at the forefront of the fight against digital fraud,” explained Ranjan Reddy, CEO and founder. “Money mule accounts, deepfake identities, account takeover, and payment fraud have surged with sophisticated AI-powered tools, impacting every corner of the digital economy. Bureau’s proprietary technology, powered by Graph Neural Networks, neutralizes these threats to the digital economy.”
