Another possible title for this blog was "I Designed A 50 Ω Transmission Path; Why is My Return Loss or VSWR Higher Than Expected?" Another was "Maintaining 50 Ohms In A Channel Is Trickier Than It Looks." Hopefully, you understand the main point we're trying to make. This blog is a summary of a seminar by Samtec's Michael Griesi, presented at IMS 2023. For those of you who weren't able to attend, a video of the full presentation is above. In the meantime, here's an overview of what Michael … [Read more...]
New Waveguide Technology for Next-Generation Systems
As end-applications venture into the sub-Terahertz spectrum, Samtec has recognized the need for a new generation of products, one that incorporates an innovative approach by integrating a cable design that can support frequencies up to 90 GHz (E-band) with loss performance improved over today's coaxial cables. Enter our next-generation micro waveguide technology, offering the near-loss performance of a rigid waveguide while still providing the flexibility and size typically associated with a … [Read more...]
Wideband 24-30 GHz Phased Array Antenna Module Demonstrates Excellent 5G Comms Link
Wideband 24-30 GHz 5G mmWave capabilities are showcased in this demo by establishing an over-the-air (OTA) communication link between two Phased Array Antenna Modules, or PAAMs. Samtec's Jim Alexander walks us through one of several live product demonstrations from IMS 2023. This one is presented with our friends at Otava, Rohde and Schwarz, Taoglas, and Avnet. The modulated 5G FR2 signal is generated using a Rohde & Schwarz SMW200A vector signal generator which is sent to the … [Read more...]
New High-Performance 90 GHz Test Solution Enables 224 Gbps PAM4 SerDes Characterization
The demand for bandwidth is pushing the limits of test and measurement to speeds and fidelity not previously possible. Complex systems, such as 5G and 6G networks, high-speed SerDes, automotive radar, artificial intelligence, machine learning, and augmented and virtual reality, require much higher frequencies for evaluation. Even though 112 Gbps PAM4 is just now becoming fully available within the market, 224 Gbps PAM4 SerDes characterization is already knocking at the … [Read more...]
Women in Microwaves Reception Draws Crowd at IMS
International Microwave Symposium (IMS) 2023 in San Diego was a busy event, incorporating an entire week of technical programming for engineers designing RF, microwave, mmWave, and THz systems. Each year, the event hosts a Women in Microwaves networking reception. This year, Samtec was fortunate enough to join Microwaves & RF magazine as the sponsors of the Women in Microwaves (affectionately referred to as “WIM”) reception, which was held at the Hilton Bayfront San Diego hotel on Tuesday, … [Read more...]
