1) MEMS Switch Development Status
Renaissance will be exhibiting its new MEMS based 8 x 8 switch matrix at the MTT-S show this year. This matrix is built using RADANT MEMS SPDT switches with a lifecycle of over 1 billion cycles. This makes it an ideal candidate for being part of a high reliability and high performance ATE system.

The expected performance from DC - 6 GHz is 2.5 dB maximum insertion loss, 30 dB isolation, 1.25:1 VSWR and 100 micro-second switching speed. The matrix is based on 100% reciprocal and blocking configurations with only switches and no dividers.

The unit is extremely compact and fits within 8" x 8" x 3" profile. Cold switch levels should not exceed 33dBm and hot switching levels cannot exceed 17dBm without impacting the long term reliability. Renaissance has incorporated a series of charge pumps which allow this matrix to be controlled using +/- 5V external biasing.

2) Cascading Single Junction Circulators

Renaissance chief engineer, Dr. Anuj Srivastava, recently composed an article  that explains the cost/performance conditions for applications requiring over 40 dB of isolation between a duplex Antenna, transmitter and the receiver. This article will be published in an upcoming issue of Microwave Product Digest, so keep your eyes peeled!


3) New Rep Training Program
Renaissance kicked off its new Brainshark Sale Reps training program at the beginning of March. Brainshark is a web-based training platform that allows Renaissance to present information in PowerPoint format with accompanying audio. It provides Renaissance with a medium to furnish all of our professional field sales representatives with timely, pertinent information for the three primary product lines. This will allow the reps to keep our customers up to date with our newest initiatives.

4) ADS-B Ferrite Applications
Over the past year and a half Renaissance has seen a significant up tick in RFQ’s for parts in the 950-1150 MHz range. The two bands used in the current air traffic control system (ATCRBS) fall in this range. Ground stations use the 1030 MHz band to monitor nearby planes and planes respond on the 1090 MHz band. The air traffic control technology of the future, Automatic Dependent Surveillance-Broadcast (ADS-B), is currently in development. The FAA is investigating three alternatives for the choice of data link technology for ADS-B, one of which is Mode S Extended Squitter, or GPS Squitter. Interestingly, Mode S also operates in the 1030 and 1090 bands. We believe that the up tick in RFQ’s for parts in the 950-1150 MHz range may be related to the switch to ADS-B and, particularly, Mode S. Stay tuned for information about our new products in this band in the very near future.


5) Mr. Shane Delmore Promoted to Product Group Manager
Renaissance Electronics is pleased to announce the appointment of Shane Delmore to the position of Product Group Manager, RF Subsystems, effective April 2007. Shane joined Renaissance Electronics in August 2004 just after graduating from MIT with a Bachelor of Science degree. At Renaissance, he started as a member of the RF Subsystems group and had a primary focus on Sprint/Nextel business development.

The Renaissance Electronics RF Subsystems Product Group has realized significant growth over the past two years. Shane has developed plans for major expansion of our RF Subsystems business in 2007 and 2008.
