Guerrilla RF Inc of Greensboro, NC, USA, which provides monolithic microwave integrated circuits (MMICs) to wireless infrastructure original equipment manufacturers for greater coverage area and higher data rates, has introduced a family of high-linearity ultra-low-noise amplifiers (Ultra-LNAs) that support wireless infrastructure devices including high-performance small-cell LNAs, macro base-station LNAs, distributed antenna systems (DAS) and general-purpose LNA applications requiring the lowest possible noise figure (NF).
“We are excited to help our wireless infrastructure customers obtain maximum receiver sensitivity and improve receiver dynamic range with minimal external components, which ultimately yields a simple and low-cost application circuit that allows for optimal efficiency and re-use,” says Alan Ake, VP of applications and technical marketing.
According to Research and Markets, the overall wireless network infrastructure market will increase at a compound annual growth rate (CAGR) of over 5%, accounting for over $104bn in annual spending by the end of 2020.
The GRF2051 Ultra-LNA (optimized for 1700–2700MHz frequencies) and the GRF2052 Ultra-LNA (optimized for 2300–3800MHz that can be tuned to 6GHz) provide what is claimed to be industry-leading NF and gain performance with simple external matching, adjustable current and flexible Vdd. Configured as a first-stage LNA, linear driver or a cascaded gain block, the 2.0mm x 2.0mm x 0.55mm devices offer high levels of reuse – within a design and across platforms.
Samples and evaluation boards are available now, with full production scheduled for second-quarter 2015. Pricing is $1.37 each in 10,000-unit quantities.
