IDT ( http://ko.idt.com/ , Country Manager Sang-Yup Lee), an analog-digital company providing core mixed-signal semiconductor solutions, has launched the latest IQ modulator for wireless products, offering the industry's lowest power consumption and highest level of linearity. The IDTF1650 connects directly to high-performance dual digital-to-analog converters (DACs) to reduce power consumption by 50 percent and lower IM3 distortion by up to 12 dB compared to competing products. This newly released product is suitable for high-performance LTE multiple-input multiple-output (MIMO) wireless communication systems that require extremely low power consumption.

In typical multimode, multifrequency base station transmitters, the limited linearity of the modulator and high power consumption have an adverse effect on the system's adjacent channel leakage ratio (ACLR) and power consumption costs in a digital prior distortion environment. IDTF1650 solves these shortcomings with embedded Zero-Distortion™ technology, enabling engineers to achieve a high OIP2 (second-order intercept point) of 60dBm and an OIP3 (third-order intercept point) of 35dBm even at very low power consumption of 500mW.

Dave Shepard, Vice President and General Manager of IDT’s Timing and RF Business Unit, explained, “IDT’s latest RF product family, which helps customers develop market-leading products, is experiencing rapid growth, and we have added the IDTF1650. The new low-power IQ modulator can significantly reduce power and performance costs by solving one of the major challenges engineers face today.”

Using MIMO with the IDTF1650 can reduce power consumption by up to 4W and improve spectral performance and error vector magnitude (EVM). This product provides high linearity and achieves a 3dB power gain while keeping added noise very low, and can be directly connected to popular JESD204B and DDR DACs.
