Guerrilla RF, Inc. has announced the production launch of its GRF5847 linear power amplifier module, a new RF solution designed for high-performance wireless, aerospace, and defense applications operating in the 4.4 GHz to 5.2 GHz frequency band.
The company said the GRF5847 represents its flagship power amplifier (PA) offering in this spectrum, combining fully integrated 50-ohm input and output matching with high output power, efficiency, and linearity in a compact surface-mount form factor. The device is fabricated on a new InGaP HBT process and packaged in a 2.5 mm x 3.0 mm LAMM-12 package.
A key design feature of the GRF5847 is its fully integrated matching architecture. The amplifier does not require external input or output matching components. This reduces board space requirements and simplifies system design. It also lowers bill-of-materials cost and overall engineering complexity.
The frequency range targeted by the device is widely used in advanced communications systems. These include high-data-rate unmanned aerial systems (UAS) payload links, upper C-band tactical radios, and n79 massive MIMO cellular infrastructure deployments. The amplifier can function as either a final-stage power amplifier or a high-linearity driver amplifier, allowing flexible integration across multiple signal-chain designs.
Ryan Pratt, Founder and Chief Executive Officer of Guerrilla RF, said the product marks a major milestone for the company. He described it as the firm’s first fully integrated amplifier solution. He added that the device advances the performance of the company’s 5V InGaP HBT technology platform while maintaining strong linearity and output power characteristics.
Pratt said customers in UAS, tactical radio, and wireless infrastructure markets have highlighted key performance advantages. These include broadband coverage, low error vector magnitude (EVM), and strong linearity compared with competing devices.
The GRF5847 operates from a single 3V to 5V supply. It delivers more than 35 dBm of saturated output power across the target frequency band. It also achieves power-added efficiency greater than 50 percent. The amplifier provides approximately 40 dB of gain and reaches 43 dBm OIP3 performance, placing it among high-linearity solutions in its category.
The company said the device’s linearity performance often reduces or eliminates the need for digital predistortion (DPD). This can simplify system architecture. It also reduces power consumption and design overhead in transmitter systems.
The integrated architecture also removes the need for external matching networks. This enables more compact layouts and faster design cycles for RF system developers. It is expected to be particularly relevant in size-constrained aerospace and defense platforms.
Guerrilla RF said the GRF5847 is gaining early traction due to its combination of power efficiency, linearity, and ease of implementation. The company positioned it as a solution aimed at next-generation high-frequency communication systems requiring both performance and integration efficiency.
The product will be showcased at IMS2026, the IEEE International Microwave Symposium in Boston, Massachusetts. The company will present the device at Booth 12070 in partnership with Richardson RFPD and Booth 18054 with RFMW.
At the event, Guerrilla RF will also highlight its broader RF semiconductor portfolio. This includes low-noise amplifiers, gain blocks, driver amplifiers, RF switches, power detectors, digital step attenuators, and digitally controlled variable gain amplifiers.
