Evaluation Board for ADL5375 400MHz to 6GHz Broadband Quadrature Modulator
ADL5375-05-EVALZ is a fully populated, 4-layer, FR4-based evaluation board. For normal operation, it requires a 5V / 500mA power supply. The 5V power supply should be connected to the clip leads labeled VPOS and GND. The LO and baseband inputs (which should be biased at 0.5V) are applied to edge-mounted SMA-type RF connectors.
The ADL5375 output drives the ADL5320 driver amplifier with its output and is available at the SMA connector labeled AMP_OUT. The ADL5375's output can be accessed directly at the SMA connector labeled AMP_IN/SMA_OUT (remove R2 and install zero ohms in R1).
The evaluation board also includes options to drive the LO differentially through a balun along with pads that can be used to implement a harmonic filter in the LO path.
ADL5375 Description
The ADL5375 is a broadband quadrature modulator designed for operation from 400MHz to 6GHz. Its excellent phase accuracy and amplitude balance enable high performance intermediate frequency or direct radio frequency modulation for communication systems
