How to design the attenuators?2022-05-10 11:23:36 点击:171 Remember the attenuator that only knows how to eat power In this paper, we introduce the technical specifications and basic structure of the attenuator. Although we don't want the precious electromagnetic wave signal to be attenuated,...
The goal is to design transmission lines that can deliver 100% of the power inserted at the beginning of the line to the antenna. To better understand the impact of the mismatch due to a characteristic impedance other than 50 Ω, see the table below. Table 1. Characteristic impedance and...
The reader will learn the physics underlying the operation of bicycle power meters and the design of the electronics. The solution described in this article has very low power consumption, is able to accurately amplify small, low frequency signals, is low cost, and has small size. Introduction...
Figure 1. Typical RF pulse showing overshoot, settling, and droop, among other characteristics. The combination of rise and fall times, peak amplitude, pulse width, and duty cycle combines to help define the range, sensitivity, thermal, and power design targets for a rad...
Testing RF power amplifier in a manufacturing setting requires a striking balance between speed and repeatability. Learn how to use the fast power servo loop and signal processing technique to streamline the test process to achieve faster throughput. ...
Telephone Design A simple telephone Howstuffworks.com The very simplest working telephone would look like this inside. As you can see, it only contains three parts and they are all simple: A switch to connect and disconnect the phone from the network: This switch is generally called the hoo...
Shure's PGA98H is a cardioid condenser instrument that you can clip on to woodwind instruments. The product includes an integrated horn clamp, a flexible gooseneck design, and a preamplifier for phantom power and XLR connection. Learn More SM137The Shure SM137 is a versatile, flat-respons...
Design Hub Menu December 19, 2017 In a previous blog post, we covered five key things to know about Wi‑Fi 6 (802.11ax), the next big standard for Wi-Fi. Let’s examine some of the challenges that RF engineers will face when designing for Wi‑Fi 6 and some tips on ho...
