The typical use of a diplexer (three port device) enables source transmitters operating on two separate frequencies to use the same antenna. In other applications, the diplexer allows a single antenna to transmit and receive on discreet frequencies. Additionally, a diplexer will provide the ability for an antenna to transmit and receive simultaneously.
When designing and manufacturing passive broadband high frequency cascaded LC filters (inductor and capacitor), a lot of undesirable component interactions can occur if not properly managed. The goal is to minimize the difference between an RF microwave filter design constructed with ideal components and one using commercial off-the-shelf (COTS) and custom manufactured components.
Printed circuit boards (PCBs) continue to shrink. As each generation of miniaturized components comes along, board designers find themselves able to work within ever-smaller PCB footprint sizes. While this is great news for consumers (compare the size of a 1994 portable phone to one of today’s models) it presents difficulties for fabricators.
Over the last 25 years, the evolution of touch screen technologies has brought sweeping changes to how society uses human-machine interface (HMI) products. Originally touch screens were small, monochrome, and required a stylus and single touchpoint to operate.
Even though the last financial crisis was over 8 years ago, most engineering departments at electronic OEMs have never fully staffed back to the levels that they were before the economic disaster. That means that there are many engineers doing two or more jobs, all while their senior management still insists on meeting tight timelines with limited budgets.
When creating your SMART user interface design, the operating environment should be taken into careful consideration. Environmental contaminants, moisture, temperature extremes, UV radiation, and overall wear and tear from use in outdoor environments are factors that should be considered before determining material and component selection for your SMART user interface.
Before designing your custom human-machine interface project, it's important to have an idea of all the steps involved before and during production. Each step has variable length so while there isn't an exact timeframe for production, having a more informed viewpoint is critical to everyone's ability for following HMI design best practices.
It is critical for any flex circuit design to be free of errors and violations in order to get the application to market as fast as possible without unnecessary delay. To help designers avoid common IPC PCB design standards violations in rigid-flex PCBs, this blog post will discuss three of the most common IPC Association Connecting Electronics Industries design violations.
Navigating through the complex cable industry can be both difficult and time consuming. This is especially true if, for whatever reason, you have to change your cable assembly manufacturers. This blog post is intended to give you a perspective of what to expect if you find yourself in the need of switching an existing cable assembly design to a new supplier.
When developing an overmold tool for a custom cable assembly, consideration needs to be given to the tactile features of the finished part. There are several areas that constitute these considerations, including the desired finish of the end part as well as the precision of the molding tool itself. The choices you make in physical features may seem insignificant, but the touch, feel, and appearance can have a real impact on the final cable assembly.
