InGa HBT power amplifiers for 5G infrastructure

The gadgets – GRF5526, GRF5526W, GRF5536 and GRF5536W –  had been designed particularly for 5G wi-fi infrastructure purposes requiring distinctive native linearity over massive 100MHz bandwidths and temperature extremes of -40°C to 105°C.

Choose variants of the GRF55xx household – together with the GRF5526W and GRF5536W – are being certified for full AEC-Q100 compliance.

By the tip of the summer season, Guerrilla could have launched a number of -W variants of its linear PAs in help of a significant contract it gained again in November.

Spanning frequency ranges of two.3–2.7GHz and three.3-4.2GHz respectively, the GRF5526 / GRF5526W and GRF5536 / GRF5536W are tuned to function inside the n7, n30, n38, n40, n41, n48, n53, n77, n88 and n90 5G new radio (NR) bands.

The gadgets usually ship 23dBm of linear energy over the whole -40°C to 105°C temperature vary whereas sustaining ACLR ranges of higher than -45dBc and EVM ranges < 1% – all with out the help of supplemental linearization schemes like digital pre-distortion (DPD).

The power to beat the -45dBc ACLR efficiency metric with out DPD is essential for mobile purposes like house and business repeaters/boosters, femtocells, and picocells, in addition to cable loss compensators that are used along side automotive ‘shark fin’ antennas.

In every of those use instances, the sensitivity to price, energy and measurement constraints prohibits the usage of elaborate linearization methods like DPD. As a substitute, designers should depend on the ability amplifier’s native linearity to satisfy the stringent emissions masks necessities imposed by the most recent 5G requirements.

“The GRF5526 and GRF5536 are strategic additions to our beforehand launched ¼ W PAs,” says Jim Ahne, Guerrilla RF’s VP of Automotive and 5G Merchandise. “With their formal introduction, we now have an entire suite of commercially accessible linear PAs addressing all bands focused by our 5G and automotive buyer base.

The GRF5536 variants are notably noteworthy since they capitalize on the rising recognition of the C-band – what many within the business hail as essentially the most engaging spectrum for 5G purposes as a consequence of its ideally suited mix of propagation protection and accessible bandwidth.”

“The brand new -W variants inside this household are additionally essential additions for our automotive enterprise,” continues Ahne. “Choose variants of the GRF55xx household – together with the GRF5526W and GRF5536W – are being certified for full AEC-Q100 compliance. By the tip of the summer season, Guerrilla RF could have launched a number of -W variants of its linear PAs in help of a significant contract it gained again in November.”

The GRF5526, GRF5526W, GRF5536 and GRF5536W are available in pin-compatible 3mm x 3mm, 16-pin QFN packages.

Samples and analysis boards can be found for all 4 parts.

Costs begin at $1.70 for the GRF5526/36 collection, and $1.95 for the ‘W’ (AEC-Q100 certified) variants (10,000-up, EXW USA).
