Guerrilla RF Begins Sampling New LNA with Selectable Gain for 5G mMIMO Applications

Latest pHEMT LNA Leverages Patented Guerrilla Armor™ Technology

Guerrilla RF, Inc. (OTCQX: GUER) announces it is sampling the GRF2176, a high gain, two-stage low noise amplifier with built-in bypass functionality. As with other bypass-capable devices within its portfolio, this LNA leverages the company’s patented Guerrilla Armor™ technology which prevents amplifiers from turning on in the presence of large RF input signals – a critical requirement for guaranteeing exceptional stage isolation and minimal impact on a device’s on-state performance.

“The GRF2176 builds directly upon the success of our previously released single-stage GRF2076 LNA with Bypass,” says Jim Ahne, Guerrilla RF’s VP of Automotive and 5G Products. “The high gain capabilities of this new device will allow our existing 5G mMIMO customers to replace two discrete cores with a single, ultra-small component. The GRF2176 core will also serve as the cornerstone of a new line of highly integrated mMIMO receiver devices which will be sampling later this summer.”

By utilizing three unique matching sets, the GRF2176 can be tuned to operate over all common 5G mMIMO bands stretching from 2.3-2.7 GHz, 3.3-4.2 GHz and 4.4-5 GHz. The bypass function allows the devices to support two selectable gain modes – a critical feature for many applications requiring a fast yet simple way to quickly reduce the overall gain in a wireless system. This flexibility is critical for applications like 5G needing to quickly shift into a low gain state to protect downstream blocks from damaging overdrive conditions.

When operating in its high gain mode at 3.75 GHz, the GRF2176 draws only 66mA of current while delivering 32.4 dB of gain, 32 dBm of OIP3 linearity, a compression level of 20.9 dBm, and a noise figure of 0.65 dB. When in bypass mode, the gain is reduced to 15.8 dB, with OIP3 and OP1dB levels of 24.9 dBm and 13.9 dBm, respectively. Noise figure performance stays relatively constant with a rating of 0.68 dB.

The GRF2176 utilizes Guerilla RF’s popular 1.5x1.5mm DFN-6 package – the company’s ultra-small packaging option supporting a common footprint for over 30 devices. The entire family of parts provide customers with a multitude of options for addressing different frequency, gain, noise figure, compression and linearity requirements. This modular approach has proven to be extremely popular with GRF’s customer base since it provides an exceptional degree of design latitude, translating directly into design speed and agility.
