1 Brief Description
The EV9900A allows evaluation of the CMX990 Baseband and RF Modem IC. The design is a flexible
platform to allow users to configure and evaluate the CMX990 for various applications and frequency
bands. Initial configuration is for 410-430MHz operation with 25kHz channel spacing and 9600bps. A
number of RF circuits, such as VCO’s, PA and LNA, are provided on the EV9900A to facilitate easy
evaluation. The PA and LNA are configurable for different operating bands through component value
changes (contact CML for further information).
Serial numbers 198189 – 198203 are supplied configured for external Auxiliary LO operation – please refer
to the “Addendum” at the end of the document for further information.
