Broadband Low Noise Amplifier

The GRF2105 can be operated over a range of Vdd from 3.0 to 5.0V and Iddq can be controlled independently from Vdd, thus allowing the device efficiency to be optimized for a given application requirement. It is internally matched to 50 ohms and can cover 700 to 2700 MHz with a single set of external […]

Ultra-LNA™ Families

The GRF207X and GRF208X families of ultra-low noise amplifiers are offered in an industry standard 2x2mm DFN-8 package. They each contain four devices internally optimized to cover the following bands: GRF2070/2080, 0.4 to 1.5 GHz; GRF2071/2081, 1.4 to 2.7 GHz; GRF2072 (above)/GRF2082, 2.3 to 3.8 GHz; and GRF2073/2083, 3.0 to 6.0 GHz.

To De-embed or Not?

by Alan Ake Vice President of Applications Engineering/Technical Marketing Guerrilla RF As applications engineers frequently supporting ultra-low noise amplifiers (LNAs), questions often arise regarding the presentation of noise figure (NF) data to customers. Clearly, de-embedding NF to the input and output pins of the amplifier results in the most impressive numbers being put forth into the […]

Broadband, Low Noise Linear Amplifier

The GRF4042 is a new broadband, low noise linear amplifier with integrated bypass that covers a wide bandwidth with minimal external parts, yielding a compact, low-cost solution. This device integrates low noise figure, high linearity and low-loss bypass functionality into a small application footprint, making it ideal for demanding small cell, cellular booster and repeater […]
