Abstract:

This letter presents a Ka-band mutual coupling resilient stacked-FET power amplifier (PA) in 45-nm CMOS silicon on insulator. Two sub-PAs with triple-stacked-FET to increase output-power (Pout) are combined through a quadrature hybrid coupler to keep robust and high performance in the scenario of mutual coupling among the phased-array antennas. A …

A Multichannel Injection-Locked OOK Transmitter With Current Mode Edge-Combining Power Amplifier

A Multichannel Injection-Locked OOK Transmitter With Current Mode Edge-Combining Power Amplifier 150 150
Author(s): Sheng-Kai Chang, Zhi-Wei Lin, Kuang-Wei Cheng

Abstract:

This letter introduces an ultralow-power ON–OFF keying (OOK) wireless transmitter incorporating innovative multiphase injection locking and frequency multiplication techniques. The transmitter leverages a current mode class-D edge-combining power amplifier, ensuring high-energy efficiency in frequency multiplication to generate the carrier frequency. With a primary focus on facilitating multichannel support for …
