As applications such as data links and satellite communications increasingly demand low-power amplifiers, system requirements for cost and efficiency are also rising. Especially in the S and C bands, where competition in amplifier specifications is intense, efficiency requirements have been raised to over 50% in many application scenarios. Against this backdrop, plastic-packaged MMIC power amplifiers have become a highly competitive solution by balancing miniaturization, low cost, and high performance.

Bonray Electronics introduces a new series of S- and C-band power amplifiers with output power from 6W to 12W, in plastic packages, combining high efficiency, high gain, and compact size. This new series can be used alone as the final stage of a transmit chain or as the driver stage for 50W and 100W internally matched power amplifiers in the same band, forming a complete link solution.

New Product Series Overview

This new series includes a total of 4 products, covering the 1.7GHz~6GHz band, with output power ranging from 6W to 12W, all in QFN24 (5mm×5mm) plastic packages.

Performance Plots

The BR9722FWJ is a high-efficiency power amplifier for S-band applications, covering 1.7GHz to 3.4GHz. The product operates from a +28V drain supply, delivers 12W output power, 35.2dB small-signal gain, and 54.8% power added efficiency, with a supply current of 240mA. It uses a QFN24 (5mm×5mm) plastic package, combining high efficiency, high gain, and compact size. It is widely applicable in Tiantong, telemetry, data link, radar, and other transmitter systems, providing a cost-effective power amplification solution for S-band transmit chains.

Core Advantages

  • High Efficiency: PAE up to 56%, meeting stringent system efficiency requirements.
  • High Gain: Small-signal gain up to 35.2dB, reducing the number of preceding driver stages.
  • Compact Plastic Package: QFN24 (5mm×5mm), suitable for medium-power driver or final-stage amplification. Leveraging high power density, it achieves unit miniaturization while ensuring detection range.
  • Flexible T/R Link Design: Can be used alone as a final stage or as a driver stage for 50W/100W internally matched power amplifiers.
