The STM32 series single-chip microcomputer is used as the controller to control the stepping motor through the L9110S motor drive module, thereby affecting the gap of the cone valve. At the same time, ...

This letter presents a dual-band complementary metal–oxide–semiconductor (CMOS) low-noise amplifier (LNA) for fifth-generation (5G) new radio (NR) frequency range 2 (FR2) applications. The proposed ...
