Guerrilla RF launches broadband, low-noise linear amplifier with integrated bypass

Guerrilla RF Inc of Greensboro, NC, USA - which provides monolithic microwave integrated circuits (MMICs) to wireless infrastructure original equipment manufacturers - has launched a broadband, low-noise linear amplifier with integrated bypass that covers a wide bandwidth with minimal external parts – yielding a compact, low-cost solution. The device integrates low noise figure, high linearity and low-loss bypass functionality into a small application footprint, making it suitable for demanding small-cell, cellular booster and repeater transmit-receive applications in the 700–3800MHz frequency bands.

"The GRF4042 is the initial device in a growing family of high-performance amplifiers offering bypass functionality," says Alan Ake, VP of applications and technical marketing. "All of our devices featuring bypass also incorporate our Guerrilla Armor technology, which provides high off-state isolation even in the presence of high RF input powers," he adds. "This isolation is especially useful in TDD systems in which significant transmitter RF power can leak into the transceiver receive path. When transmitting in a TDD system, the powered-down LNA chain needs to stay off regardless of the level of incident power from the PA. Our GRF4042 addresses this requirement nicely with off-state S (2,1) typically less than -30dB with input powers in excess of +15 dBm."

According to analyst firm 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 by the end of 2020.

The GRF4042 provides sub 1.0db noise figure, excellent linearity, adjustable current, low-loss bypass and Guerrilla Armor. With integrated DC blocking caps on the RF input/output and internal pre-matching to 50Ω, the device typically requires little or no external matching.

Samples and evaluation boards are available now, with production planned for fourth-quarter 2015. Pricing is $0.98 each in 10,000-unit quantities.
