MiniRF Inc. has introduced the MRFXF0589 miniature high performance transmission line transformer for RF wireless markets. The MRFXF0589 is a broadband 50 Ohm 1:1 transformer that covers a 5 MHz to 3 GHz frequency range. Its unique electrical characteristics provide RF designers with better return loss, lower insertion loss and a smaller package than our popular RFXF9503. Its footprint is 20 percent smaller than the RFXF9503, along with a 0.5 dB reduction of insertion loss at 3 GHz. Additionally, the MRFXF0589 return loss is improved to at least 15 dB across the band with improved amplitude and phase balance. This transformer targets synthesizers, mixers, output amplifiers and other balanced RF circuit applications. This next-generation 50 Ohm balun offers high performance without the need for circuit complexity.
MiniRF products are 100 percent RF tested. This, plus MiniRF’s controlled manufacturing techniques and quality materials, inspire confidence in the company’s ability to provide high volume, low-cost products. A ferrite core that provides sufficient low frequency inductance, along with low insertion loss over a broad operating temperature range, is a key element in this product design. This design incorporates other components and strict assembly techniques to ensure proper impedance and consistent high-frequency performance.

These and other design and manufacturing techniques ensure that the designer gets a reliable and effective component. Designing with the MRFXF0589 enables radio designers to develop high performance radio systems without costly components. This balun can be used in multiple applications to provide many advantages to wireless designers. Contact MiniRF or RFMW for this new broadband product.
