+===============
+
+USB-Powered, 5.8 GHz RF Power Amplifier with Overtemperature Management
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+Overview
+--------
+
+The :adi:`EVAL-CN0523-EBZ <CN0523>` is a USB-powered, RF power amplifier 
+that is optimized for transmitting signal chains in the 5.8GHz ISM band. 
+Using two :adi:`HMC407` amplifiers cascaded together, the design
+provides a gain of 28dB and return losses of more than 10dB throughout its RF
+band of operation.
+
+An overtemperature management feature is implemented on the
+:adi:`EVAL-CN0523-EBZ <CN0523>` wherein the amplifiers are
+automatically disabled when the board temperature reaches a preset threshold,
+and it automatically returns to normal operation once the temperature falls
+below the hysteresis point.
+
+Designed to be used with the :adi:`ADALM-PLUTO`, or other
+software defined radio platform, the board features a small form factor, with
+dimensions of 25.4mm×50.8mmx1.5748mm (PCB only). The RF input and output
+are designed with a 50Ω impedance, enabling direct connection between the
+circuit and standard 50Ω systems.
+
+A micro-USB connector is used for the input power, allowing the evaluation board
+to use most 5V wall wart power supplies available in the market.

+
+SMA Connectors
+^^^^^^^^^^^^^^
+
+The SMA connectors are used for the RF input and output connections:
+
+   - **J1** is the **RF Input** SMA male connector that would be connected to a
+     radio or piece of RF equipment. The maximum RF input level of the
+     :adi:`EVAL-CN0523-EBZ <CN0523>` is **+10dBm**. Do not use a higher input
+     level to avoid damaging the circuit.
+
+   - **J2** is the **RF Output** SMA FEmale connector that would be connected to
+     an antenna. The saturated output power (Psat) of :adi:`EVAL-CN0523-EBZ <CN0523>` 
+     is **+27dBm**. Ensure that the RF load can handle the amplified RF signal. 
+     Use an RF attenuator if necessary to avoid damage.
+
+LED Indicators
+^^^^^^^^^^^^^^
+
+- The reference design uses two LEDs to indicate its current status:
+

+   LED Indications of Board Status

+   **DS1**                         **DS2** **Board Status**
+   Off                             Off     No power
+   Off                             On      Normal operation
+   On                              On      Overtemperature

+Power Supply Connector
+^^^^^^^^^^^^^^^^^^^^^^
+
+- **P1** is the micro-USB port used to provide 5V power to the board. The total
+  typical supply current of the on-board RF amplifiers is 230mA.
+
+Changing the Temperature Switch Trip Point (JP1, JP2, JP3)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- The trip point of the temperature switch can be set using the solder jumpers
+  JP1, JP2, and JP3 as shown in the table below. When the board temperature
+  reaches the trip point, the :adi:`ADT6401` will disable the two RF
+  amplifiers.

+
+Getting Started
+---------------
+
+Required Equipment
+~~~~~~~~~~~~~~~~~~
+
+**Hardware**
+
+- :adi:`EVAL-CN0523-EBZ <CN0523>`
+- :adi:`ADALM-PLUTO`
+- Two (2) micro-USB power adaptors or micro-USB to USB cables for powering
+  :adi:`ADALM-PLUTO` and :adi:`EVAL-CN0523-EBZ <CN0523>`
+- One (1) SMA male-to-male cable
+- One (1) SMA 30 dB RF attenuator
+
+**Firmware**
+
+- For step-by-step procedure on how to update the Pluto Firmware, you can
+  use this :dokuwiki:`user guide link </university/tools/pluto/users/firmware>`. 
+  The latest firmware version for the **ADALM-PLUTO** can be found here:
+
+   .. admonition:: download
+
+      ADALM-PLUTO Firmware:
+      `Pluto version latest release <https://github.com/analogdevicesinc/plutosdr-fw/releases/latest>`__
+
+- In order to properly operate the ADALM PLUTO, you need to setup and configure
+  it. Follow the procedure through this
+  :dokuwiki:`link </university/tools/pluto/users/firmware>`.
+
+Test Setup
+~~~~~~~~~~
+
+#. Connect directly the **TX port** of :adi:`ADALM-PLUTO` to the
+   **RF Input (J1)** of the :adi:`EVAL-CN0523-EBZ <CN0523>`.
+#. Connect directly the **RX port** of the :adi:`ADALM-PLUTO` to
+   a 30dB attenuator.
+#. Connect **RF Output (J2)** of the :adi:`EVAL-CN0523-EBZ <CN0523>` to a 30dB
+   attenuator using a male-to-male SMA cable.
+#. Connect **P1** (micro-USB) connector of the :adi:`EVAL-CN0523-EBZ <CN0523>`
+   into a PC USB port or a 5V USB charger.
+#. Connect the micro-USB to USB cable to a PC/laptop and the other end to the
+   :adi:`ADALM-PLUTO` data port.
+#. The DS2 LED of :adi:`EVAL-CN0523-EBZ <CN0523>` will automatically
+   turn on, indicating that the board is powered on and is in operation.
+#. Refer to the image below for the full hardware setup.

+
+      EVAL-CN0523-EBZ Test Setup
+
+.. warning:: 
+
+   Connecting the CN0523 directly to the PlutoSDR input (Rx) 
+   may result in an exceedance of its absolute maximum ratings
+   of +2.5dBm. Such an action may lead to permanent damage to the PlutoSDR. It is
+   strongly recommended to use a **30dB or 40dB attenuator** at the RX input of
+   the ADALM PLUTO to avoid incurring damage.
