Low-power IQ modulator til den næste generation af wireless systemer
IDT lancerer IQ modulator, der ifølge firmaet bl.a. udmærker sig med markedets hidtil mindste effektforbrug (in english).
Integrated Device Technology (IDT) has 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, says 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.
The IDTF1650 is available now in a compact 4x4 mm 24-ld VFQFPN package. http://www.idt.com/go/RF
