Guerrilla RF releases new 5 to 8 GHz LNA with industry-leading noise figure and linearity performance

08 December 2023

Guerrilla RF, Inc. has unveiled the GRF2110, an ultra-low noise amplifier (LNA) that delivers an exceptionally flat gain response over a single 5 GHz to 8 GHz broadband tune.

When operated at 6 GHz, the device delivers 16.3 dB of gain, 22 dBm of OP1dB compression, 38 dBm of OIP3 linearity, and a low noise figure of 1.2 dB (as measured on the device’s standard evaluation board; de-embedded noise figure (NF) values are approximate 0.2dB lower). As with most of GRF’s amplifier cores, the GRF2110 touts a flexible biasing architecture allowing for customizable tradeoffs in linearity and powerSource: Guerrilla RF, Inc.Source: Guerrilla RF, Inc. consumption. Supply voltages can vary between 2.7 V and 6 V, although most customers will elect to use a standard 5 V supply with 70 mA of biasing current.

“Given its native operating band, the GRF2110 will be a compelling LNA for satellite communications, aeronautical telemetry, radar, industrial scientific medical (ISM), WiFi 6E, and 5G cellular infrastructure applications targeting new n96, n102 and n104 bands in the 5.9 GHz to 7.2 GHz range,” said Jim Ahne, vice president of automotive and 5G products at Guerrilla RF. “In each of these end markets, customers are continuously seeking LNA cores offering an excellent blend of low noise, high linearity and high compression performance — critical for enhancing a system’s overall receiver sensitivity while overcoming link impairments due to blocker interference.”

The GRF2110 utilizes Guerilla RF’s popular 1.5 mm x 1.5 mm dual flat no-leads (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 is extremely popular with GRF’s client base since it provides an exceptional degree of design latitude, translating directly into design speed and agility.

Pricing and availability

Samples and evaluation boards are available for the GRF2110. Prices start at $1.76 (10,000-up, EXW U.S.).
