Types, Working, and Selection of DC Motor27 March 2025
A direct current motor (DC motor) is an electric motor that operates on direct current. The operation of an electric motor is based on basic electromagnetism. When a current-carrying conductor is put in an external magnetic field, it will feel a force that is equal to the current in the conductor and the frequency of the external magnetic field.
Operational Amplifier Basics: Working Principle and Amplifier Circuit21 March 2025
Operational amplifier (referred to as "op amp") is a circuit unit with very high magnification. In actual circuits, a certain functional module is usually combined with a feedback network. It is an amplifier with a special coupling circuit and feedback. The output signal can be the result of mathematical operations such as addition, subtraction, differentiation, and integration of the input signal. Because of its early application in analog computers to realize mathematical operations, it was named "operational amplifier".
Understanding the Low Noise Amplifier (LNA)20 March 2025
A low noise amplifier is an amplifier with a very low noise figure. It is generally used as a high-frequency or intermediate-frequency preamplifier for various types of radio receivers, as well as amplifying circuits for high-sensitivity electronic detection equipment.

Adopting GaN/Si MMIC in Space-based Applications14 June 2024
When it comes to satellite technology, multiple applications comprising commercial to scientific domains rely heavily on efficient microwave front-ends, particularly in high-frequency bands like Ku- to Ka-bands. In satellite communication, the development of highly efficient power amplifiers (PAs) is crucial, considering the limited power supply available onboard satellites, mostly from solar cells and batteries. However, achieving power efficiency poses significant challenges, especially in high-frequency operations, which often need different enhancement approaches. Moreover, ensuring high reliability and longevity is crucial for sustained operation over several years or even decades, requiring compliance with derating rules to mitigate stress on electronic systems.
