Setting Strategies For Transmission Lines
Last month, the first part of this article made recommendations for choosing the physical dimensions of stripline. A large height, H, ensures high power-handling capability. Smaller H requires a smaller strip for the same impedance, leading to higher losses. The thickness, h, of the suspended stripline dielectric substrate should be as small to minimize losses and parasitic inductance of vias, as well as to reduce cost. For slotline, the...

Setting Strategies for Transmission Lines
Transmission lines are often taken for granted in the design of high-frequency circuits and integrated circuits (ICs), since the focus is often on getting signals into and from an active device. But by understanding the capabilities of different microwave/RF transmission lines and how to optimize them, design iterations, time, and unnecessary cost can be saved from a project. Part 1 of this two-part article will show how a careful design process should...

Assemble A Tunable L-Band Preselector
Electrically tunable preselectors are key elements in communications, avionics, and radar receivers. Narrowband RF and microwave preselectors prevent large off-channel signals from overdriving a receiver front end. Microstrip combline and...
