Guerrilla RF launches automotive-qualified ultra-LNA for SDARS, compensator and GPS applications

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 launched the GRF2073-W as a new addition to its growing list of AEC-Q100 automotive-qualified amplifiers.

The ultra-low-noise amplifier is targeted at high-volume applications, with first-stage satellite radio LNAs and GPS modules being prime examples. Offered in an industry-standard, ultra-small 2.0mm x 2.0mm DFN-8 package, it shares a common pin out with other infrastructure-class devices from Guerrilla RF.

The GRF2073-W can operate over a range of Vdd of 2.7-5.0V, and Iddq can be controlled independently from Vdd, allowing the device efficiency to be optimized for a given application requirement. The device can cover 2300-2700MHz with a single set of external components with gain of 20.5dB, OP1dB of 20.0dBm, NF of 0.40dB at 2300MHz with bias at 5.0V and 70mA. Flexible biasing can accommodate Vdd of 2.7-5.0V and Iddq of 20-100mA.

The new amplifier for automotive applications addresses an industry need for a cost-effective, first-stage LNA delivering outstanding RF performance with low power consumption over a wide frequency range, claims the firm. “The device’s ultra-low-noise figure capability is critical for achieving the difficult cascaded NF specification for digital audio satellite radio service (SDARS) receivers in the 2320-2345MHz band,” says Alan Ake, VP of applications and technical marketing. “Furthermore, simple matching along with the 2.0mm DFN-8 package results in a compact application footprint.”

GRF2073-W samples and evaluation boards are available now. Pricing for 10,000 parts is $1.25.

According to Technavio’s Global Automotive Antenna Module Market report, the market is expected to rise steadily at a compound annual growth rate (CAGR) of 7.66% to 1,549.24 million by 2021, driven by several factors, including the rise of wireless connectivity in vehicles, the rising adoption of embedded cellular connectivity, the drive toward autonomous vehicles, economies of scale advantage in satellite antennas, the legislative push to have eCall in cars, and the growing popularity of the truck platooning system. Additionally, the average age of car buyers in developed regions like USA in increasing, owing to higher disposable income.
