Guerrilla RF Inc of Greensboro, NC, USA – a provider of radio-frequency integrated circuits (RFICs) and monolithic microwave integrated circuits (MMICs) for wireless applications – has added to its family of low-current, low-noise amplifiers and linear drivers with two devices that are tunable over 100-3800MHz, each exhibiting what are claimed to be outstanding gain and noise figure with a typical bias condition of 3.3V and 15mA.

The new broadband, low-noise linear amplifiers, with and without integrated bypass, cover a wide bandwidth with minimal external parts – yielding a compact, low-cost solution. They integrate a low noise figure, good linearity and low-loss bypass functionality into the firm’s small DFN-6 (1.5mm x 1.5mm) application footprint, making it suitable for demanding small-cell, cellular booster and repeater transmit-receive applications in the 700–3800MHz frequency bands.

The new LNAs/linear drivers address a growing industry need for cost-effective, broadband, discrete amplifiers delivering strong, consistent performance over a wide range of operating conditions. “With flexible biasing (Vdd = 2.7-5.0V; Iddq = 10-25mA), these amplifiers provide consistent performance at low currents and very competitive prices,” says Alan Ake, VP of applications and technical marketing.

The GRF2373 and GRF2374 comprise Guerrilla RF’s initial product offerings utilizing indium gallium phosphide heterojunction bipolar transistors (InGaP HBTs).

Samples and evaluation boards are available now, prior to production in fourth-quarter 2019. Pricing is $0.40 and $0.42 each (in 10,000-unit quantities) for the GRF2373 and GR2374, respectively.

Following this introduction of the firm’s InGaP HBT portfolio, additional announcements will be made in the coming months about new power amplifier products, notes Ake.

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