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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

May 20, 2016 - Optenni Ltd announces a new version of the Optenni Lab™ matching circuit optimization and antenna analysis software featuring a new workflow for the optimization of switchable matching circuits.
After seven years of intense development, Optenni Lab has become the leading professional matching circuit optimization software on the market, with many unique innovative features that are not found in any other software. With Optenni Lab 3.3, we have added new features and usability improvements to speed up the antenna design flow.
Optenni Lab now supports the optimization of frequency tunable matching circuits and tunable filters, where the tuning is implemented by switches. Previously, impedance tuners, tunable capacitors and simplified switch models were supported by Optenni Lab but the new version adds full support for the use of multiport SPNT switches. Setting up the optimization is fast and easy: the engineer enters the desired operating frequencies for the various switch states, reads in the switch model from an MDIF file (containing all the switch states) and inserts the other components of the switchable matching circuit. Optenni Lab then optimized the component values so that the best possible efficiency is obtained for all the switch states. Optenni Lab also supports complex switches which have advanced states like "all off" or simultaneous connections between the common port and multiple RF ports.
"Optenni Lab 3.3 contains many usability improvements which have been requested by our customers. But we are especially excited about the improved support for switchable matching circuits", said Dr. Jussi Rahola, founder and CEO of Optenni Ltd. "We see increasing interest in the design of tunable and switchable matching circuits. To support this, we provide the end user with a streamlined design flow for state-of-the-art switch technologies."
Optenni Lab 3.3 is available as of now. Visit our web page to find your local reseller of Optenni Lab.
