Sub-1 GHz radio links sit at the core of a wide range of products, including public safety radios, smart utility meters, RFID readers, and vehicle telematics units. Many of these systems now need to work across several regional frequency allocations without a hardware redesign for each market, while still running efficiently on battery power in a compact footprint. Qorvo's QPA9510 power amplifier is built around that requirement.
The QPA9510 is a general-purpose amplifier covering 100 MHz to 1000 MHz, spanning GSM, E-GSM, UHF, and FM bands. Because the device supports this whole range while remaining tunable to specific sub-bands, a single design can be adapted for different regional frequency plans rather than starting from scratch for each one.
On performance, the QPA9510 delivers up to 34 dB of gain with more than 70 dB of analog gain control range, and it maintains linear operation up to a 1 dB compression point of roughly +35 dBm. It runs from a single supply (2.8 V to 4.8 V per its recommended operating conditions) and reaches efficiency of up to 55%. The part is fabricated on Qorvo's GaAs process and housed in a compact 3 mm x 3 mm QFN package, making it suitable for space-constrained designs.
To help designers evaluate the part, Qorvo also offers the QPA9510EVB evaluation board, tuned for the 865 MHz to 928 MHz range to assess GSM performance. The board includes the biasing and control circuitry needed to run the amplifier, along with RF input/output connectors, analog gain control, and single-supply operation, letting engineers test gain, output power, efficiency, and linearity without building supporting circuitry themselves.
