EV9920 Evaluation Kit for CMX992

Brief Description
The EV9920 allows the evaluation of the CMX992 quadrature/low IF receiver. The CMX992 includes only the receiver and IF LO sections of the CMX991 and is ideal for applications that do not require the CMX991 transmitter, for example when a linearised transmitter is required, in which case the CMX998 Cartesian loop transmitter IC could be used for Tx and the CMX992 for Rx.

Access is provided to all CMX992 RF, baseband and control signals by either connector or test points. Test access points are available to accpt common test equipment, such as RF and baseband signal generators and spectrum analysers. All signal paths are matched by suitable components.
The overall evaluation frequency range of this evaluation kit is for RF frequencies between 100MHz and 1GHz, with default operation over 450MHz to 470MHz. In the form of a populated PCB, this flexible evaluation kit enables users to configure and evaluate the CMX992 for various applications and frequency bands.

The on-board CMX992 is controlled via its C-BUS serial interface. The PE0002 interface card is available seperately to support PC-based control of the EV9920. The PE0002 uses ES9910xx.exe PC software, part of the ES9910xx.zip file, which is available from the CML website.
