The QPB9378 from Qorvo covers 5G’s mid band, seen as the sweet spot for range and bandwidth.
The GFR5317 linear power amplifier boosts signals in 5G repeaters, antenna systems, and automotive “shark fins.”
Digital predistortion compensates for an amplifier’s nonlinearities, letting it operate in its nonlinear region for maximum power efficiency.
Sivers Semiconductors’ TRB02801 and TRB03901 provide a complete baseband-to-antenna signal chain, covering 28 GHz and 39 GHz. 5G Technology World spoke with CEO Anders Storm about the RFIC functions and applications.
The AM1111 amplifier from Atlanta Micro provides 16 dB of gain from 2 GHz to 18 GHz. You can cascade multiple amplifiers to boost signals as needed. Powered by +5 V and packaged in 3 mm QFN package, the AM1111’s input and output provide a 50-Ω DC-blocked impedance.It consumes 500 mW and has a 2.5…
The low-power QFP4526 and high-power QFP4568 bring switches, filters, and amplifiers to Wi-Fi 8 (802.11ax) designs. Wi-Fi 6 (IEEE 802.11ax) access points, routers, gateways, customer-premise devices, and IoT devices need amplifiers to boost signal power to its final levels. The QFP4526 and QFP4568 front-end modules from Qorvo operate at 3.7 V and 5 V power…
Pasternack’s PE15S70xx variable-gain RF amplifiers bring output power up to 48 dB, depending on model.
The AMM-7199 and AMM-7200 series from Marki Microwave drive downstream components in mmWave RF systems
A hybrid International Microwave Symposium (IMS) took place live in Atlanta and online two weeks later in June 2021. See a selection of companies and product — mostly 5G — showcased in the virtual version.
Multi-chip module integrates GaN on top of LDMOS to improve power amplifier energy efficiency.
