Changes
 LO input level specified to -20dBm for operation above 200MHz.
 Editorial corrections
 Extra information on third order intermodulation added.
 Note added for clarification in Figure 4 / Figure 4a.
 Added note 32 to AC Parameters section, identifying a drop in gain and output
power below a frequency of 100MHz - typically 4dB down at 30MHz.
 Differential Amplifier connections in Figure 4 and Figure 4a corrected.
 Operating characteristics clarified for Tamb rather than Tcase and at 25degC
only for notes 0 and 1.
 Current consumption specification reduced, following test of several wafer
batches.
 Editorial corrections, Modulator Common Mode input range minimum now 1.3V
and Input/Filter Amplifiers ‘Input Offset’ specification updated.
 Updated inline with abbreviations and pin assignments document
 CMX993W wide-bandwidth product variant included
 Lowest operating frequency specified as 30MHz
 Change to pin out and Signal List
 Original document, first approved.
