EV9930 Evaluation Kit for CMX993 RF Quadrature Modulator

Brief Description
The EV9930 evaluation kit allows for rapid and full evaluation of the CMX993 quadrature modulator IC by providing a populated PCB with access to all CMX993 RF, baseband and control signals by either connectors or test points. Test access points are available to accept common test equipments such as RF and baseband signal generators and spectrum analysers. Control of the CMX993 is by registers which are accessible over the C-BUS interface (an SPI™-like serial interface). A PE0002 interface card (not supplied) allows the C-BUS interface to be controlled from a PC, via its USB port. Alternatively, the C-BUS interface can be controlled by an external microprocessor.

RF signal paths are matched by suitable components and the operating frequency range of the evaluation kit is for RF frequencies between 100MHz and 1GHz. The EV9930 baseband inputs can be configured to work with the CMX910 AIS baseband processor IC or the CMX981 digital radio baseband processor IC; standard test equipment or with a custom baseband system.

Preliminary Information
The EV9930 provides a platform for the evaluation of the CMX993. To use the EV9930, a separate micro-controller or PC is required to program the CMX993 via its C-BUS interface. This controlling device is not included on the EV9930, but a PE0002 Interface Card (not supplied) will provide the controlling functionality from a PC, via its USB port.

Laboratory Equipment
The following laboratory equipment is needed to use this evaluation kit:
Power supply (dual power supply if using PE0002).
Spectrum analyzer (100MHz to 1GHz)
RF signal generator (100MHz to 2GHz)
I/Q quadrature signal source
For more detailed design or investigation work the customer may require other RF test equipment.
