-======EVAL-CN0566-RPIZ Overview======+====== CN0566 Phased Array User Guide ======
  
-[[ADI>CN0566]] is an RPi-based 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]], a low noise amplifier (LNA) that operates from 6-18GHz with 1.3dB NF and 24 dB gain. The 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 GHz, 4-Channel, beamformer that allow per-channel, 360° phase adjustment with 2.8° resolution and 31dB gain adjustment with 0.5dB resolution.  The ADAR1000s are capable of bidirectional, half-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 applications. This places a greater importance on training engineers and rapidly prototyping new phased array concepts. However, both those imperatives have historically been difficult and expensive. That 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 education, project proposals, and even software development.\\ 
 +Most of the labs are run on a Python GUI, with several helper scripts. These can be run on a remote host computer, or directly on the phaser's Raspberry Pi computer with the addition of a keyboard, mouse, and display.\\ 
 +For more advanced application development, the Phaser is also supported in the MATLAB RF Microwave Toolbox. Equivalent MATLAB lab exercises are in development, and 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. \\ +Here is a brief video introduction to beamforming and the Phased Array Platform:

-EEPROM_ID sets the EEPROM I2C address. It consists of P4, P5 and P6 solder jumpers connected respectively to A2, A1 and A0 address selection pins of U7. The default address configuration is “111”. This EEPROM I2C address is configurable from 001 to 111.
