The FMC238 uses a single ADRV9009 to provide dual transmitter, dual receiver and dual observation receiver. The FMC239 uses two ADRV9009 to provide quad transmitter and quad receiver, but without the observation receivers.
The ADRV9009 features dual channel Transmitters (TX) and Receivers (RX) with integrated synthesiser and digital signal processing functions. Each complete RX and TX subsystem includes DC offset correction, Quadrature Error Correction (QEC), and programmable digital filters. The transceivers also provide Automatic Gain Control (AGC) and flexible external gain control modes, allowing significant flexibility in setting system level gain dynamically.
The FMC238/239 operates within the 75MHz to 6.0GHz frequency range, covering most licensed and unlicensed bands. The clocking is via the front panel or an internal clock. This makes the FMC238/239 an ideal choice for the development and/or deployment of advanced RF solutions.
