New GRF5607/8 PAs Deliver ½ W of Linear Power for 5G without DPD


First in a Series of New InGaP HBT Power Amplifiers from GRF Provide 26dBm of Natively Linear Output Power for 5G Applications that Cannot Employ DPD, CFR or ET

Guerrilla RF, Inc. (OTCQX: GUER) announces the formal release of the GRF5607 and GRF5608, the first in a new class of ½ W linear power amplifiers being developed by the company.  These InGaP HBT amplifiers were designed specifically for 5G wireless infrastructure applications requiring exceptional native linearity over temperature extremes of -40°C to 85°C.

Spanning frequency ranges of 703-748MHz and 746-830MHz, respectively, the GRF5607 and GRF5608 are tuned to operate within the n12, n14, n18, n20 and n28 5G new radio (NR) bands. The devices typically deliver 26dBm of linear power over the entire -40°C to 85°C temperature range while maintaining ACLR levels of better than -45dBc and EVM levels < 1.2% – all without the aid of supplemental linearization schemes like digital pre-distortion (DPD).

The ability to beat the -45dBc ACLR performance metric without DPD is critical for cellular applications like home and commercial repeaters/boosters, femtocells, and picocells, as well as cable loss compensators which are used in conjunction with automotive ‘shark fin’ antennas. In each of these use cases, the sensitivity to cost, power and size constraints prohibits the use of elaborate linearization techniques like DPD. Instead, designers must rely on the power amplifier’s native linearity to meet the stringent emissions mask requirements imposed by the latest 5G standards.

“The GRF56xx series directly builds upon the market success of the company’s previously released ¼ W family of power amplifiers,” says Jim Ahne, Guerrilla RF’s VP of Automotive and 5G Products. “As announced last November, Guerrilla RF has made significant inroads into the automotive cellular market, and these power amplifiers represent a significant piece of its established business. By essentially doubling the output power, GRF is enabling customers to increase the range of their systems by up to 40%. Given that these new devices are pin-pin compatible with the previously released GRF55xx series, customers now have an easy path to upgrading the range capabilities of their existing repeater/booster and compensator platforms. The new series also ensures Guerrilla RF maintains its dominant position within this rapidly growing market segment.”

The GRF5607 and GRF5608 come in pin-compatible 3mm x 3mm, 16-pin QFN packages.
