Part 1 looked at the basics of RS-232. This part continues that examination, along with some extensions to the standard and test issues. Q: What are some of the issues associated with RS-232 and its performance? A: The standard allows for many user choices in how the DTE and DCE are configured: number of data […]
Making sense of thermocouples and interfaces (Part 1)
Temperature is the most frequently measured real-world variables, and despite its age, the thermocouples are still among the most-used temperature sensors. They are used in test and measurement equipment, instrumentation, and even in standard home ovens due to their low cost, reliability, simplicity, and ability to measure into the hundreds of degrees. What is a […]
SAW filters target Wi-Fi use with steep skirts, minimal insertion loss
Murata Manufacturing Co., Ltd. has released a new Incredibly High Performance (IHP) SAW filter (measuring just 1.1 x 0.9 mm) for Wi-Fi applications that delivers greater steepness, insertion reduction, and temperature characteristic stability compared to conventional models. Using the company’s new proprietary SAW technology to achieve these benefits, the SAFQ2G45MA0G0A series is ideal for ISM2.4GHz RF circuits in mobile devices, such as smartphones […]
How should grounds and commons be connected to each other?
We have already looked briefly at Earth ground (if any), chassis ground, and commons (often misnamed as “grounds”). These do not exist as unrelated connections in a system. The issues related to connecting commons and ground is the subject of countless articles, academic papers, vendor application notes, anecdotes, and even books. There are many rules […]
Tiny 15-W low-pass integrated thin-film filters span 512 – 1,800 MHz
AVX Corporation, a leading manufacturer of passive components and interconnect solutions, has released a new series of 15W high performance, low pass integrated thin film (ITF) SMD filters that exhibit low insertion loss and extremely sharp attenuation in high-frequency wireless applications spanning 512MHz to 1,800MHz. Featuring a miniature 2816 chip size with a maximum height […]

AFE simplifies complex programming algorithms, extends life of industrial equipment
Analog Devices, Inc. introduced a highly integrated polyphase analog front end (AFE) with power quality analysis designed to help extend the health and life of industrial equipment while saving developers significant time and cost over custom solutions. Achieving extremely accurate, high-performance power quality monitoring typically requires customized development, which can be expensive and time-consuming. The […]
750 MHz SMD low-pass filter sports low insertion loss
AVX Corporation has released a new 750MHz 0805 high performance, low pass integrated thin film (ITF) SMD filter that exhibits low insertion loss and extremely sharp roll-off in high frequency wireless applications spanning 746MHz – 756MHz, including: mobile communications systems, microcell and picocell base stations, satellite TV receivers, global positioning systems (GPS), vehicle location systems, […]
Digital filters vs. Analog filters
Digital and analog filters both take out unwanted noise or signal components, but filters work differently in the analog and digital domains. Analog filters will remove everything above or below a chosen cutoff frequency, whereas digital filters can be more precisely programmed. Analog filters that remove signals above a certain frequency are called low pass […]
