Guerilla RF adds 0.1 W PA at IMS
The GFR5317 linear power amplifier boosts signals in 5G repeaters, antenna systems, and automotive “shark fins.”
How DPD improves power amplifier efficiency
Digital predistortion compensates for an amplifier’s nonlinearities, letting it operate in its nonlinear region for maximum power efficiency.
5G RFICs take mmWave from baseband to antenna
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.
Amplifier boosts signals from 2 GHz to 18 GHz
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…
Wi-Fi 6 RF front ends combine functions
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…
