-======EVAL-CN0566-RPIZ Overview======+====== CN0566 Phased Array User Guide ======
  
-[[ADI>CN0566]] is a phased-array beamforming antenna demonstration platform that allows the user to experience the principles and applications of phased array antennas. +===== Introduction =====
  
-The RF input signal is received from an onboard 8 element patch antenna that operates from 10 to 10.5 GHz. Each antenna element is input to an [[ADI>ADL8107]], low noise amplifier (LNA) that operates from 6-18GHz with 1.3dB NF and 24 dB gainThe output of these amplifiers are fed into the main core of this circuitry, two of the [[ADI>ADAR1000]]The [[ADI>ADAR1000]] is an 8 GHz to 16 GHz4-Channelbeamformer that allow per-channel360° phase adjustment with 2.8° resolution and 31dB gain adjustment with 0.5dB resolution.  The ADAR1000s are capable of bidirectionalhalf-duplex operation However[[ADI>CN0566]] only connects the ADAR1000 receive paths The outputs of four LNAs get phase and amplitude shifted by an [[ADI>ADAR1000]]then summed together at its RFIO output+Phased array communications and radar systems are finding increased use in a variety of applicationsThis places greater importance on training engineers and rapidly prototyping new phased array conceptsHowever, both those imperatives have historically been difficult and expensiveThat is why Analog Devices launched the ADALM-PHASER It is a low cost, simplified phased array radar which allows real beamforming hardware to be used for educationproject proposalsand even software development.\\ 
 +Most of the labs are run on a Python GUI, with several helper scriptsThese can be run on a remote host computer, or directly on the phaser's Raspberry Pi computer with the addition of a keyboardmouse, and display.\\ 
 +For more advanced application development, the Phaser is also supported in the MATLAB RF Microwave ToolboxEquivalent MATLAB lab exercises are in developmentand will be added below as they are completed.
  
-The ADAR1000's RFIO output passes through a low pass filter before entering the [[ADI>LTC5548]] mixer.  The low pass filter removes the high side image of the mixer as well as any re-radiation of the high side LO.  [[ADI>LTC5548]] outputs an IF of approximately 2.2 GHz which passes through a low pass filter (LPF) to remove mixer spurs and attenuate any RF or LO leakage. The LPF's output, at Rx1 and Rx2, can then be mixed down and sampled by an external 2-channel SDR receiver, such as the ADALM-Pluto. +{{ :resources:eval:user-guides:circuits-from-the-lab:cn0566:phaser_with_topics.png?600 |}}
- +
-The system consists of the EVAL-CN0566-RPIZ, Raspberry Pi 3 or 4 running ADI Kuiper Linux, an ADALM-Pluto Rev. C, 5V power source, and either keyboard/mouse/monitor OR separate host connected via VNC. The Raspberry Pi 4 provides all SPI, I2C, and discrete digital I/O control signals. \\ +
