Demand for long-range, portable wireless communication is growing across markets such as public safety radios, smart utility metering, RFID logistics and telematics. Designers face mounting pressure from these industries to support multiple regional bands, extend battery life and minimize form factors.
Qorvo’s QPA9510 is a new RF power amplifier (PA) that aims to meet these new demands. The QPA9510 delivers wideband coverage from 100 to 1000 MHz with an efficiency of 55 percent, enabling a longer runtime in battery-powered radios and IoT devices. The amplifier provides +36 dBm output power and 34 dB gain for link budgets in space-constrained systems.
The QPA9510 is designed for use as the final RF amplifier in Global System for Mobile Communications (GSM) hand-held equipment in the 900 MHz band and other applications in the ultra-high frequency (UHF) bands. By replacing multiple discrete PAs with one device, the QPA9510 reduces SKU count, simplifies board design and accelerates time to market for next-generation sub-1 GHz systems.
An analog on-board power controller provides over 70 dB range of gain adjustment for simplified system calibration and tuning. This control also allows for power down with a voltage equal to the logic “Low” to set the device in standby mode. The QPA9510 is tunable over any sub-bands in the operating range to optimize performance. The amplifiers sit in a 3 mm x 3 mm compact quad-flat no-lead (QFN) package.
When combined with Qorvo’s low noise amplifiers, digital step attenuators and RF switches, the QPA9510 enables complete RF front-end solutions for transmit-and-receive chains in linear communication systems.
