At IMS 2021 in Atlanta, Guerrilla RF introduces the GRF5517, GRF5518, and GRF5519, three new ¼ W linear power amplifiers for the cellular market. These new InGaP HBT amplifiers were designed specifically for 5G/4G wireless infrastructure applications requiring exceptional native linearity at a temperature range from -40°C to 85°C.
Spanning the frequency range of 1.7-1.8 GHz, 1.8-1.91 GHz, and 1.92-2.0 GHz respectively, the GRF5517, GRF5518, and GRF5519 are tuned to operate within the n1, n2, n3, n25, n39, n65, n66, and n70 5G new radio (NR) bands. The amplifiers typically deliver 23 dBm of linear power over the entire -40°C to 85°C temperature range while maintaining ACLR levels of better than -45 dBc, IMD3 levels < -20 dBm, EVM levels < 1.5%, and PAE Efficiencies > 14%–all without the aid of supplemental linearization schemes like digital pre-distortion (DPD).
The ability to beat the -45 dBc ACLR performance metric without DPD is critical for cellular applications like home and commercial repeaters/boosters, femtocells, picocells, and cable loss compensators associated with automotive ‘shark fin’ antennas. In each of these use cases, the sensitivity to cost, power, and size constraints prohibit 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 and 4G standards. During the development of the GRF55xx series, Guerrilla RF consulted directly with its base of customers to ensure the devices delivered the best blend of power and linearity, thus maximizing the effective range and throughput for their cellular systems. Guerrilla RF also designed the entire family of devices to be fully footprint compatible, enabling its customer base to rapidly customize its designs for a myriad of cellular frequencies.
