The Renesas family of RF mixers featuring patented Zero-Distortion™ technology dramatically improves the maximum signal levels (IM3 tones) that a receiver can withstand at a desired Signal to Noise Ratio (SNR.) These devices are scalable, so alternately, one can run the devices in modes that reduce power consumption significantly while still maintaining high linearity.
Renesas offers active mixers with excellent out-of-band spur performance which eases pre-filtering requirements. RF and LO baluns are internal allowing for simple 50ohm interfaces. The IF ports are configured as differential 200ohms to drive pre-ADC filters with low even-order distortion. Solutions are available in both dual mixer and single mixer configurations.
2 x 2 and 3 x 3 spurs: These in-band spurs cannot be filtered so the RF mixer must provide all of the rejection for the system. The Renesas family of RF mixers provides very high rejection (>70dB) to these critical spurs.
Robust power down modes: The Renesas active mixers can be fully turned on and off in <200nsec, which is ideal for modern TDD systems. Furthermore, the LO port impedance is practically unchanged in the off state which minimizes the potential for synthesizer pulling.
Scalability: In addition to multiple modes of operation, all Renesas mixers include external resistor options for further down-scaling the power consumption vs. linearity. Application notes that describe how to reduce the current further and still maintain >32dBm OIP3 are available on the product pages.

IDT's RF to IF downconversion dual mixers significantly benefit BaseStation vendors and operators. Featuring IDT Zero-Distortion™ technology, intermodulation Distortion is reduced up to 19 dB (98% at the device level, 83% at the system level) while power consumption is reduced up to 40% to 1150 mW. IDT's RF to IF downconverting mixers are pin compatible with competitor's devices and are offered in 3 versions to cover any of the UTRA bands from 700 MHz to 2700 MHz allowing for a compelling upgrade option.
