USING THE ADL5372 QUADRATURE MODULATOR

The evaluation board contains an Analog Devices ADL5372

quadrature modulator. The AD9776A/AD9778A/AD9779A

and ADL5372 provide an easy-to-interface DAC/modulator

combination that can be easily characterized on the evaluation

board. Solderable jumpers can be configured to evaluate the

single-ended or differential outputs of the AD9776A/AD9778A/

AD9779A. This is the default configuration from the factory

and consists of the following jumper positions:

•

JP2, JP3, JP4, JP8—unsoldered

•

JP14, JP15, JP16, JP17—soldered
