RF Micro Devices 10.0 - 16.0 GHz GaAs pHEMT I/Q converters

RF Micro Devices has released a portfolio of 10.0 - 16.0 GHz GaAs pHEMT I/Q converters, the first in a series of microwave radio front ends to be launched by RFMD for wireless backhaul applications.

The broadband frequency performance of RFMD’s newest I/Q converters enables a single product to support multiple radio bands. This allows users to access one part across multiple radio systems, simplifying inventory management.

Each converter features I/Q mixer topologies to reduce unwanted sideband filtering and supports IF frequencies from DC to 4 GHz.

The front ends are the RFUV5945A, the RFRX5933A and the RFMX5986A.

The RFRX5933A targets receive applications and is an integrated 10.0 - 16.0 GHz downconverter comprising a low-noise amplifier, I/Q image rejection mixer and LO buffer amplifier.

The broadband device exhibits a noise figure of 2 dB while maintaining 13 dB conversion gain, 25 dBc of image rejection and IIP3 performance of 3 dBm. With an input power of -20 dBm, the converter offers a minimum IMD3 performance of -50 dBc.

The RFMX5986A 10.0 - 16.0 GHz I/Q mixer integrates an LO buffer amplifier. Offering a conversion loss of 8 dB, 25 dBc of image rejection and IIP3 performance of 25 dBm, it is suitable for designers wishing to use a stand-alone MMIC or discrete LNA.

The RFUV5945A targets transmit applications and is an integrated 10.0 - 16.0 GHz upconverter comprising an I/Q image rejection mixer, LPA and LO buffer amplifier. It delivers a conversion gain of 13 dB.
