The AD-PZSDR2400TDD-EB is affectionately dubbed the first 'RF personality card'. It plugs into the Avnet AES-PZSDRCC-FMC-G carrier card. 35mm U.FL coaxial cables connect the card to the Avnet PicoZed SDR Z7035/AD9361 SOM providing access to the transmit and receive inputs of the AD9361. Information on the card, how to use it, the design package that surrounds it, and the software which can make it work, can be found here.
The purpose of the AD-PZSDR2400TDD-EB is to provide the user with a tunable path to condition the transmit or receive signals of the AD9361. Selection of TX or RX path is achieved by the 200MHz to 2.7GHz SPDT switch HMC546LP2 controlled by the FPGA and accompanying software. The transmit path consists of a 2.4GHz filter, half watt driver amplifier ADL5324 and 2 watt power amplifier HMC921. The receive path consists of the same 2.4GHz filter as well as a low loss LNA HMC669.
People who follow the flow that is outlined, have a much better experience with things. However, like many things, documentation is never as complete as it should be. If you have any questions, feel free to ask.
All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection.
Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.
