allows customers to use one part across multiple radio systems, greatly simplifying inventory management.
Additionally, each new I/Q converter features I/Q mixer topologies to reduce unwanted sideband filtering and support IF frequencies from DC to 4GHz, helping to simplify the radio design process.
RFMD’s newest available microwave radio front ends are the RFUV5945A, the RFRX5933A and the RFMX5986A. The RFUV5945A and RFRX5933A are available in a compact 5mm x 5mm QFN package, and the RFMX5986A is offered in a fully-moulded 4mm x 4mm QFN package.
The RFRX5933A, available in a 5mm x 5mm QFN package, targets receive applications and is an integrated 10.0 GHz - 16.0 GHz downconverter comprising a low noise amplifier (LNA), I/Q image rejection mixer and LO buffer amplifier. It exhibits a noise figure of only 2dB while maintaining 13dB conversion gain, 25dBc of image rejection and IIP3 performance of 3dBm. With an input power of -20dBm, the RFRX5933A offers radio designers a minimum IMD3 performance of -50dBc.
The RFMX5986A is offered in a fully-moulded 4mm x 4mm QFN package The 10.0 GHz - 16.0 GHz I/Q image rejection mixer integrates an LO buffer amplifier. Offering a conversion loss of 8dB, 25dBc of image rejection and IIP3 performance of 25dBm, it is an ideal partner for designers wishing to deploy a standalone MMIC or discrete LNA.
The RFUV5945A is available in a 5mm x 5mm QFN package and targets transmission applications. It is an integrated 10.0 GHz -- 16.0 GHz upconverter comprising an I/Q image rejection mixer, LPA and LO buffer amplifier. The RFUV5945A delivers OIP3 of up to 24dBm and a conversion gain of 13dB.
RFMD’s 10.0 GHz - 16.0 GHz I/Q converters deliver superior levels of integration to enable

smaller radio board footprints, decreased design time and automated board assembly. The I/Q converters are ideally suited for current- and next-generation microwave radio applications.
Samples and pre-production quantities are available now through RFMD’s online store or through local RFMD sales channels. The RFUV5945A is priced at $19.97 in volumes of 10,000; the RFRX5933A is priced at $18.75 in volumes of 10,000; and the RFMX5986A is priced at $11.35 in volumes of 10,000.
Kaai fly with new blue laser
The company will introduce it’s latest blue laser and provide an update on its green laser commercialization at ‘Projection Summit 2010’ in Las Vegas, Nevada on June 7, 2010.
California based firm Kaai, announced shipments of its new blue laser diode for display and specialty applications.
The company will describe its latest products in a presentation entitled “The Emergence of Direct Emitting Green and Blue Semiconductor Lasers for Display Applications.”
Based on InGaN, and fabricated on GaN substrates, new blue laser diode is designed for integration into portable applications such as embedded and companion pico projectors and features 60 mW of 445 nm single mode output power in a compact TO‐38 package.
The lasers are claimed to operate with high efficiency and require minimal power consumption over a broad temperature range, meeting the demanding requirements of many imaging applications, defense pointers and illuminators and biomedical instrumentation.
