0.25-W linear PAs and LNAs target automotive cellular compensators
Guerrilla RF has released two ¼ W linear PAs and two LNAs earmarked specifically for the automotive market. All four devices were qualified to meet rigorous AEC-Q100 quality standards.
These new PAs and LNAs are used primarily in cellular compensators (essentially cellular ‘signal boosters’ serving to amplify and enhance cellular signals within the cabin of vehicles).
The GRF5507W and GRF5517W join the previously announced GRF5526W and GRF5536W linear PAs. Together, the four devices cover the most popular cellular bands spanning the 700 MHz to 4200 MHz frequency range. These components are derivatives of GRF’s recently released ¼ W PA family — the primary difference is these new cores have been subjected to an additional set of qualification tests and unique production screening protocols to warrant an AEC-Q100 Class 2 rating.
The GRF55xx-W series of PAs are ideal for 4G/5G cellular applications requiring exceptional native linearity over temperature extremes of -40°C to 105°C. Each of these devices can deliver up to 23 dBm of output power with better than -45 dBc of ACLR performance — all without the aid of supplemental linearization schemes like digital pre-distortion (DPD). The ability to beat the -45 dBc ACLR performance metric without DPD is critical for meeting the stringent size, cost and power dissipation requirements of these cellular compensator/compenser applications.
The new GRF2106W and GRF2133W also complement GRF’s existing portfolio of fully qualified AEC-Q100 LNAs. The GRF2106W is rated to operate over the 2700 to 5000 MHz range with a nominal gain of 21.5 dB and a low NF of 0.8 dB. A higher gain level of 28 dB is available with the GRF2133 providing an even lower NF of 0.6 dB over an operating band of 1800 to 5000MHz.
“Completing the qualification of these devices has been a critical step for Guerrilla RF as we continue to gain share within the automotive space,” says Jim Ahne, Guerrilla RF’s vice president of automotive and 5G products. “Together, these AEC-Q100 compliant devices extend the GRF’s reach into the growing market for 5G cellular compensators associated with automotive shark fin antennas. Given the introduction of these new AEC-Q100 qualified PA and LNA cores, we’ve now formally released six of seven components tied directly to previously announced cellular compensator/compenser contract which will be ramping later this year.”
The GRF5507W and GRF5517W PAs come in pin-compatible 3- x 3-mm, 16-pin QFN packages, while the GRF2106W and GRF2133W LNAs are available in a tiny 1.5- x 1.5-mm, 6-pin DFN package. Samples and evaluation boards are available for all four components.
