Greensboro, N.C. – August 25, 2020 –
Guerrilla RF introduces the
one of ten new ¼ W linear power amplifiers being released over the next two
quarters 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 a frequency range of 700-800 MHz, the GRF5507 variant is tuned
to operate within the n12, n14, n28 and n29 5G new radio (NR) bands. The device
can deliver over 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 <
-20 dBm, EVM levels < 1% and PAE Efficiencies > 15% – 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
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 GRF5507'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 5 W
InGaP HBT 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 RF's expansion 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.
Pricing and Availability Samples and evaluation boards are available now for
the GRF5507. Prices start at $1.55 (10,000-up, FOB USA). Visit
