Product Details

The AD-PZSDR2400TDD-EB is a 2.4GHz TDD analog module designed to work with the AD9361, a high performance, highly integrated RF transceiver intended for use in RF applications, such as 3G and 4G base station and test equipment applications, and software defined radios. The AD-PZSDR2400TDD-EB is affectionately dubbed the first 'RF personality card'. It plugs into the ADRV1CRR-FMC carrier card. 35mm U.FL coaxial cables connect the card to the ADRV9361-Z7035 SDR 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 on the wiki page.

The purpose of the AD-PZSDR2400TDD-EB is to provide the user with a 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 HMC546 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.
