Automotive-qualified LNA has low-noise capability for SDARS

AEC-Q100 automotive-qualified amplifiers, the GRF2073-W have been added by Guerrilla RF. The low noise amplifier (LNA) is targeted at high volume applications, such as first stage satellite radio LNAs and GPS modules. It is offered in an industry-standard 2.0 x 2.0mm DFN-8 package, sharing a common pinout with other infrastructure-class devices from Guerrilla RF.

The amplifier for automotive applications addresses an industry need for a cost-effective, first-stage LNA delivering RF performance with low power consumption over a wide frequency range, says Guerrilla RF. The device’s low noise figure capability is critical for achieving the difficult cascaded NF specification for digital audio satellite radio service (SDARS) receivers in the 2320 to 2345MHz band.

According to Technavio’s Global Automotive Antenna Module Market report, the market is expected to grow steadily at a compound annual growth rate of 7.66 per cent to 1,549.24 million by 2021, fuelled by the rise of wireless connectivity in vehicles, the adoption of embedded cellular connectivity, the drive toward autonomous vehicles, economies of scale advantage in satellite antennae, the legislative push to have eCall in cars, and the growing popularity of the truck platooning system.

The GRF2073-W can operate over a range of Vdd from 2.7 to 5.0V and Iddq can be controlled independently from Vdd, allowing the device efficiency to be optimised for a given application requirement, says Guerrilla RF.

The device can cover 2300 to 2700MHz with a single set of external components with gain of 20.5dB, OP1dB, 20.0dBm, NF of 0.40dB at 2300 MHz with bias at 5.0V and 70mA.

Flexible biasing can accommodate Vdd from 2.7 to 5.0V and Iddq from 20mA to 100mA.

GRF2073-W samples and evaluation boards are available now.

Guerrilla RF provides high performance monolithic microwave integrated circuits (MMICs) to wireless infrastructure original equipment manufacturers in enterprise/carrier-class wi-fi access points, small cells, wireless backhaul and cellular repeaters.
