Evaluation Kit for CMX990
EV9900A
Adjacent Channel Rejection (ACR)
ACR performance is limited by local oscillator phase-noise.
Typically, 72dB ACR can be demonstrated for 25kHz channels with GMSK, Bt = 0.5 and 9.6kbit/s
using the on-board VCO. Enhanced performance can be achieved using an external, low noise,
main LO.
Intermodulation
Typically greater than >65dB tested as EN 300 113.
Spurious Response Rejection
A front-end SAW filter is not provided on the default configuration EV9900A so spurious response
rejection is not guaranteed. However the option to fit a filter to reject such responses (type
selected by user) is available. The resulting performance will depend upon the operating band
used and the particular rejection characteristics of the chosen filter.
Blocking or Desensitisation
Blocking performance is approx. 86dB.
