IDT’s Latest RF Signal Path Solution Features
Zero-Distortion™ Technology to Deliver Industry’s Lowest Power
Consumption Modulator
Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), 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.
Pricing and Availability
The IDTF1650 is available now in a compact 4x4 mm 24-ld VFQFPN
package. For more information about IDT’s broad portfolio
