New LNA delivers industry-leading noise figure and linearity performance

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

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

“Given its native operating band, the GRF2110 will be a compelling LNA for satellite communications, aeronautical telemetry, radar, ISM, WiFi 6E, and 5G cellular infrastructure applications targeting new n96, n102 and n104 bands in the 5.9GHz to 7.2GHz range,” says 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 device uses the company’s 1.5mm x 1.5mm DFN-6 package – its ultra-small packaging option supporting a common footprint for over 30 devices. The entire family of parts provides customers with many options for managing different frequency, gain, noise figure, compression, and linearity requirements.
