Guerrilla RF launches family of high-linearity gain blocks

Guerrilla RF Inc of Greensboro, NC, USA, which provides monolithic microwave integrated circuits (MMICs) to wireless network infrastructure original equipment manufacturers, has launched a new line of high-linearity broadband gain blocks that feature what is claimed to be industry-leading linearity and saturated output power along with a low noise figure (NF). 

The GRF2013 (2.7–8.0V) and GRF3013 (industry-standard SOT-89 at 5V) exhibit what is reckoned to be outstanding broadband NF, linearity and return losses over a frequency range of 50-3800MHz. Internally matched to 50 ohms, the gain blocks only need external direct current blocks and a bias choke on the output. Custom tuning/evaluation board data and device s-parameters are available.

The devices enable a number of general-market designs including small cells, cellular repeaters, LTE/WCDMA linear driver amplifiers, high-power saturated power amplifier (PA) drivers and other wireless infrastructure applications over a wide range of frequencies. Configured as driver amplifiers or cascaded gain blocks, the devices offer the potential for high levels of reuse within a design and across platforms.

"Our SOT-89 based GRF3013 offers a drop-in replacement to relatively expensive industry-standard gain blocks," says Alan Ake, VP of applications and technical marketing. "GRF2013, with its extended high voltage capability, serves as an outstanding saturated driver amplifier for broadband gallium nitride PA devices."

According to Research and Markets, the overall wireless network infrastructure market will increase at a compound annual growth rate (CAGR) of over 5% to more than $104bn by the end of 2020.

Samples and evaluation boards are available in June, with full production scheduled for third-quarter 2015.  Pricing is $1.48 for the GRF2013 and $1.10 for the GRF3013 each, respectively, in 10,000-unit quantities.
