Picking up where we left off in Part 1, we need to explore some methods to mitigate problems caused by unpredictable ground currents. Let’s start with some simplification, although we may need to first complicate things to then simplify them. First, let’s arrange a massive ground plane around the analog circuitry on the PC board.

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 […]

Clock oscillator achieves 0.2 ppm frequency tolerance
Depending on temperature range, the SiT7910 Super TCXO from SiTime can attain frequency stability of less than 0.1 ppm. Clock oscillator circuits serve two functions. They provide a clock timing signal for digital circuits such as microprocessors and they keep track of time, often for time-stamping of events. While oscillators for digital circuits typically produce […]
Where are cloud connected relays used?
Relays are humble devices, but they are not immune to being impacted by the Internet of Things. Electromechanical relays, solid-state relays, and MEMs relays are among the numerous devices in the IoT that can connect to the cloud. Some relays include Wi-Fi controllers or Bluetooth, some use power over Ethernet (PoE), and others use voice […]
Wideband, log periodic, directional antennas handle bandwidths of 600 to 6,000 MHz
Fairview Microwave has expanded its line of wideband, log periodic antennas that operate from 600 to 6,000 MHz for point-to-point wireless communications. Fairview’s new, outdoor-rated, directional antennas function as boosters where the existing cellular signal is weak and needs to reach longer distances. This makes them ideal for strengthening 5G, 4G, LTE, CMDA, LoRA, IoT, and Wi-Fi signals. […]
