RFICs improve in-vehicle communications
Two linear power amplifiers (PAs) and two low-noise amplifiers (LNAs) from Guerrilla RF serve as signal boosters to enhance in-cabin cellular signals. Qualified to AEC-Q100 Grade 2 standards, the GRF5507W and GRF5517 PAs and the GRF2106W and GRF2133W LNAs operate over a temperature range of -40°C to +105°C.
The GRF5507W power amp has a tuning range of 0.7 GHz to 0.8 GHz, while the GRF5517W spans 1.7 GHz to 1.8 GHz. Each device delivers up to 23 dBm of output power with adjacent channel leakage ratio (ACLR) performance of better than -45 dBc. Further, this ACLR figure is achieved without the aid of supplemental linearization schemes, like digital pre-distortion (DPD). According to the manufacturer, the ability to beat the -45-dBc ACLR metric without DPD helps meet the stringent size, cost, and power dissipation requirements of cellular compensator applications.
The GRF2106W low-noise amplifier covers a tuning range of 0.1 GHz to 4.2 GHz, and the GRF2133W spans 0.1 GHz to 2.7 GHz. At 2.45 GHz (3.3 V, 15 mA), the GRF2106W provides a nominal gain of 21.5 dB and a noise figure of 0.8 dB. A higher gain level of 28 dB is available with the GRF2133W, along with an even lower noise figure of 0.6 dB at 1.95 GHz (5 V, 60 mA).
Prices for the GRF5507W and GRF5517W PAs in 16-pin QFN packages start at $1.54 in lots of 10,000 units. Prices for the GRF2106W and GRF2133W LNAs in 6-pin DFN packages start at $0.62 and $0.83, respectively, in lots of 10,000 units. Samples and evaluation boards are available for all four components.
