United States : IDT Announces Low-Power IQ Modulator for Next-Generation Wireless Communications

June 6, 2014



Integrated Device Technology, Inc. (IDT®), the Analog and Digital Company delivering essential mixed-signal semiconductor solutions, today introduced a new IQ modulator that delivers the industry s lowest power consumption and highest linearity for today s wireless products. The IDTF1650 interfaces directly to high-performance dual digital-to-analog convertors (DACs), offering up to 50 percent reduced power consumption, with IM3 distortion decreased by up to 12 dB, compared to competitive offerings. The device is ideal for high-performance LTE multiple-input multiple-output (MIMO) wireless communications systems that require ultra-low power consumption.

In typical multi-mode, multi-carrier base station transmitters, the modulator has limited linearity and high power consumption, which negatively impact a system s adjacent channel leakage ratio (ACLR) and power consumption budgets in a digital pre-distortion environment. With its embedded Zero-Distortion technology, the IDTF1650 is designed to eliminate these penalties, enabling engineers to achieve a very high second order intercept point (OIP2) 60 dBm and third order intercept point (OIP3) 35 dBm with very low power consumption 500 mW

The IDTF1650 joins our fast-growing portfolio of advanced RF devices designed to help our customers develop market-leading products, said Dave Shepard, vice president and general manager of the Timing and RF Division at IDT. Addressing one of the biggest challenges engineers face today, our new low-power IQ modulator enables engineers to hit increasingly tight power and performance budgets.

A MIMO implementation with the IDTF1650 will result in up to 4 watts of power consumption savings, better spectral performance, and improved error vector magnitude, or EVM. The device offers ultra-high linearity, features 3dB of power gain with very low added noise and interfaces directly with popular JESD204B and DDR DACs.
