[4] 一篇利用Smith Chart补偿Passivity与Causality的专利技术Smith Chart can be used to monitor the passivity and causality of networks under study. For instance, Foster's reaction theorem dictates a general motion in the clockwise direction with frequency for the parameters of an arbitrary network.[5...
This chart is meant to give the RF and system engineer an opportunity to optimize sample rate, carrier frequency, and bandwidth decisions in a coherent way that can optimize the receiver’s performance. When a combination of those parameters is selected that avoids HD2 and HD3, then the ...

The RF switches by Analog Devices, Inc., which are implemented in the silicon on insulator (SOI) process, offer reflective, absorptive, and asymmetric functions that lead to higher frequency or power handling for wireless communications, aerospace or defense, and instrumentation...

An RF PCB design is a bit different from a conventional board. It is more susceptible to signal integrity issues and performance degradation due to high-frequency operations. As an RF engineer, you must carefully consider factors such as material selection, trace layout, impedance control, and th...
The eight-segment electrode (see Figure 1b) has been designed to satisfy the condition of constructive interference between the mechanical modes that improve the transduction of rf signals into the optical output within the frequency band between the two mechanical resonances. As described in [7],...
