Newest InGaPPHBT Power Amplifiers from Guerrilla RF Provide 24 HBT
Power Amplifiers from Guerrilla RF Provide 24 dBm of Output Power for Cellular
Applications Requiring Exceptional Native Linearity over Temperature Extremes
Greensboro, N.C. – January12,
2021 –12, 2021 – Guerrilla
RF introduces the
GRF5508 and GRF5510,
two of ten new ¼ W linear power amplifiers being released as part of the company's
expansion into the cellular market. These new InGaP HBT amplifiers were designed
specifically for 5G/4G wireless infrastructure applications requiring exceptional
native linearity over temperature extremes of -40°C to 85°C.
Spanning frequency ranges of 800-900 MHz and 880-960 MHz respectively,
the GRF5508 and GRF5510 are tuned to operate within the n5, n8, n18, n20 and
n26 5G new radio (NR) bands. The devices can deliver 24 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 < -17 dBm, EVM levels <
1% and PAE Efficiencies > 14% – 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, 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 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 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
their designs for a myriad of cellular frequencies.
When describing the motivation behind the GRF5508/10's development, Ryan
Pratt, CEO and founder of Guerrilla RF, stated, "The GRF55xx family builds upon
the groundbreaking work which we started a year ago with the release of the
GRF5504/9 series of 5W InGaPPHBT power amplifiers. These new ¼ W PAs were created
specifically to meet the needs of our strategic customers in the cellular and
automotive industries. Together with the original GRF5504/9 series, the GRF55xx
family will serve as the beachhead for Guerrilla RFHBT power amplifiers. These

into the growing power amplifier market."
The GRF55xx family comes in pin-compatible 3 mm x 3 mm, 16-pin
QFN packages. As noted above, the common footprint enables a single design to
address multiple bands via simple component swaps.
