    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Anatech Electronics July 2021 Newsletter

Anatech Electronics July 2021 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his July 2021 newsletter that features his short op−ed entitled "Wi-SUN: The Most Pervasive Wireless Technology You May Not Heard Of," where he notes "Like ZigBee, WirelessHART, ISA100, SNAP, and 6LoWPAN, Wi-SUN (doesn't even have a Wikipedia entry yet) is based on the IEEE 802.15.4 standard and employs a mesh-type rather than star topology, making it inherently self-healing. There is no need for base stations because each node talks to the others, eliminating a single point of failure." Not only haven't I heard of Wi-SN, but I haven't heard of WirelessHART (HART = Highway Addressable Remote Transducer) or ISA100. Sam also presents some relevant industry news items as well...

Spectrum Analyzers Check 5G Occupied Bandwidth

Axiom Blog: Spectrum Analyzers Check 5G Occupied Bandwidth - RF CafeAxiom Test Equipment, an electronic test equipment rental and sales company, has published a new blog post entitled "Spectrum Analyzers Check 5G Occupied Bandwidth" that informs people on how the right spectrum analyzers can help locate the interference of additional signal energy that can interfere with 5G service. With a suitable spectrum analyzer, occupied bandwidth measurements reveal the total integrated all signal energy within the bandwidths that concern 5G system designers, service providers, and users and when any interfering signals are at high enough power levels to be a concern. Selecting a spectrum analyzer for occupied bandwidth testing is a matter of matching the equipment's capabilities to the limits of the OBW measurements. An analyzer's frequency range and amplitude range are good starting points for 5G OBW measurements...
