Several models from our SLE series of 10 mm surface mountable circulators and isolators are part of a Super-Miniature UHF wireless transmitter systems. The unique “circulator/isolator” is included in the output stage to prevent IM products from being generated in the output amplifier. It allows the RF signal to be transmitted but will not let external RF signals back into the output amplifier.

These systems are used on shows such as Desperate Housewives, Oprah, Survivor, and CSI. This super small transmitter with the Renaissance ferrite parts is used by performers in theaters, stage, and movies.

Renaissance Electronics Switch Product Group recently manufactured and shipped high reliability switches to the NATO Maintenance Supply Agency (NAMSA) in support of NATO defense forces in Europe.

The switches on this system are another follow-on order for switches that provide extremely good reliability and durability. Renaissance Electronics is being selected by a number of government agencies and prime contractors to be their preferred switch supplier.

Renaissance Electronics a leading provider of integrated waveguide assemblies and components is developing an S-Band integrated waveguide assembly. This integrated assembly will contain an absorptive filter containing dielectric loaded secondary waveguides. The filter is designed to attenuate undesirable harmonic signal levels at the second, third and fourth harmonic citations. Following the filter are multiple dual junction circulators ganged together using ferrite resonators to realize the necessary center frequency of operation. Loop couplers are used to monitor forward and reverse power levels, and are a good way to realize signal sampling in a compact space with reasonable directivity. The assembly uses an aluminum alloy material, which is then brazed to minimize corrosion. This integrated assembly is used in military radar systems.

Renaissance Electronics has designed a high-power lumped element circulator for digital TV transmitters. The circulator has been tested up to 500 watts with excellent RF performance. As the operational bandwidth is very narrow and the frequency of operations is approximately 97 MHz, a lumped element design approach was used for this application.

The circulator prevents high power transmitter from any reflection providing a 25 dB isolation. This Circulator is available in frequencies from 88 MHz through 108 MHz. and is the first high power lumped element circulator developed for digital TV applications.
