Updated : 2022-01-24

The recent global outbreak of the novel coronavirus (COVID-19) has a serious impact on businesses worldwide, including the RF/Microwave industry. We saw some of the major events of the RF/Microwave industry being cancelled or rescheduled, such as MWC Barcelona 2020, EDI CON China 2020, RF& Microwave

How to improve the efficiency of RF power amplifier?
Updated : 2022-01-24

The essence of Doherty's technology is that it uses two transistors of the same kind, and only oneworks at small inputs, at high efficiency. If the input is large, both transistors work at the same time.The basis of this method is that the two transistors should cooperate well. The working state of

How to improve the frequency stability of microwave signals
Updated : 2022-01-24

For a long time researchers all over the world have been committed to improving the frequency stability of microwave signals to achieve high-precision and reliable operation of electronic devices or systems.

Laser Radar
Updated : 2022-01-24

LiDAR is a radar system that emits laser beams to detect the location and speed of a target. Modern 3D lidar sensors combine high horizontal longitudinal andradial resolution and are key components of L4 and L5 autonomous vehicles.

Updated : 2022-01-24

In a communication system, the mixer (frequency converter) plays a key role. The mixing circuit includes three components: local oscillator, nonlineardevice and band-pass filter.

Frequency-Hopping Spread Spectrum
Updated : 2022-01-24

Communication or remote control is achieved through radio frequency signals emitted from space. It takes up a certain frequency, and the spectrum isvery limited. The more apps you have, the more likely you are to crash. There are many effective ways to reduce mutual interference.
