Does 32 kHz or 3.58 MHz mean anything to you? part 1
These two frequencies played major roles in electronics; one is still very viable, while the other is completely obsolete. Engineers are surrounded by countless standard frequencies, many of which are defined by an industry standard. Some are so well-known and commonplace that they need no clarification other than the frequency number itself; others were “celebrities” […]
Eco-friendly radio wave absorbers manufactured with biomass material
TDK Corporation has launched the IS-BP series of radio wave absorbers, incorporating over 25 wt% of biomass material to offer an environmentally sustainable option that facilitates CO₂ reduction. Mass production of this series began in April 2024. Microwave anechoic chambers, used for evaluating antennas, wireless communication equipment, and millimeter-wave radar for AD and ADAS, have […]
Active baluns bridge the microwave and digital worlds
To achieve the datasheet performance of ultra-high-speed data converters, now clocking to 64 GS/sec, the handoff to and from the microwave domain must be near perfect. To preserve the data converters’ spurious-free dynamic range, a new category of component has been developed that converts between the differential and single-ended signal domains while amplifying and filtering […]

How many types of radar are there?
Radio detection and ranging (radar) uses reflected radio waves to detect and determine the distance, angle, and velocity of objects relative to the radar system. A basic radar system consists of a transmitter producing electromagnetic waves in the radio or microwave spectrum (these can be pulsed or continuous), a transmitting antenna, a receiving antenna (often […]
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 […]
