IDT has IQ modulator for next gen wireless communications
An IQ modulator, designed to deliver the industry's lowest power consumption and highest linearity, has been launched by IDT.
The IDTF1650 interfaces directly to high performance dual D/A convertors, offering up to 50% reduced power consumption and significantly lower IM3 distortion compared to similar devices.
The modulator is suitable 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 high second order intercept point (OIP2) of 60dBm and third order intercept point (OIP3) of 35dBm with very low power consumption (500mW).
