Analog Devices introduced the AD9164 digital-to-analog converter (DAC) that brings high-resolution radar images for designers of military and commercial radar.
Additionally, for designers of precision instrumentation equipment, such as smartphone testers, the new device ensures improved accuracy as well as speed of test. Thanks to its audio to 6 GHz frequency coverage, Analog Devices boasts that the AD9164 moves the tester market one step closer to a universal wireless test platform.
The reduction in solution component count and thus size enables element level digital beamforming advanced radar solutions. With the same performance specifications as the already released AD9162, the AD9164 also includes an on-chip direct digital synthesiser (DDS) that ensures phase-coherent fast frequency hopping of less than 300 ns for up to 32 different frequencies. This makes the DAC well suited for testing anything from AM broadcast band or Japanese FM band to 5,8 GHz UNII band.
The AD9164 features a 2x interpolator (FIR85), which enables configurability for lower data rates and converter clocking to reduce overall system power and ease filtering requirements. In mix-mode operation, the device can be configured to reconstruct RF carriers in the 2nd and 3rd Nyquist zones up to 7,5 GHz while maintaining exceptional dynamic range.
The AD9164 also comes with a unique remote evaluation tool, allowing designers to ‘test drive’ the converter’s performance. The remote tool is available at http://labs.analog.com/ad916x
