If you are working with antennas, here are some tools to consider, Part 2
Antenna design and integration is an important activity for 5G telephony, wireless Internet of Things (IoT) nodes, Wi-Fi networks, near field and satellite communications, and a range of other applications. Without robust antenna designs and solid system integration, the performance of those applications can be severely compromised. Balancing the needs for efficiency, gain, bandwidth, pattern […]
If you are working with antennas, here are some tools to consider, Part 1
Antenna design and integration is an important activity for 5G telephony, wireless Internet of Things (IoT) nodes, Wi-Fi networks, near-field, and satellite communications, and various other applications. Without robust antenna designs and solid system integration, the performance of those applications can be severely compromised. Balancing the needs for efficiency, gain, bandwidth, pattern characteristics, and decreased […]
When to buffer and when to drive signals
Buffers and drivers both provide impedance transformation between the input and output. The differences begin to appear when looking at the common types of buffers and drivers, for example, voltage and current buffers, clock buffers, line drivers, and gate drivers. Basic buffers and drivers have one input and one output, but there are others that […]
How to specify and use analog switches
An analog switch is an IC that can be used to control connections to analog and digital signals. These switches provide bidirectional connections when “on” and high impedance paths when “off.” There’s a wide range of analog switches for special functions. In some instances, they are used in place of mechanical switches. In other embodiments, […]
How do comparators and op amps compare?
Operational amplifiers (op amps) and comparators have two inputs, inverting and noninverting, and an output that can usually swing from rail to rail and have the same schematic symbol. So, what’s the difference? This FAQ compares the two devices and digs into some of the similarities and differences. It begins with a top-level comparison of […]
How to specify and use voltage references
Voltage references are small components that can have a significant impact, either positive or negative, on system performance. They are precision devices that maintain a constant voltage output even in the presence of changes in temperature, input voltage, and other external parameters. When measuring the analog world, voltage references ensure that data converters, detection circuits, […]
What’s the difference between transceivers and transponders?
Transceivers and transponders are types of communication devices. They can operate with RF or optical technologies. They are used in various environments, from terrestrial to undersea and outer space. Basic transceivers and transponders provide two-way links in various types of networks. Specialized devices like muxponders increase available bandwidth, extend network reach, and improve network efficiency. […]
