Notes:
1. Typical values defined as a typical process, Case temperature at 25C and Vcc at 3.3V while max. and min. values are under the worst or best case process, Power supply and junction temperature for the parameter specified.
2. The state performance should be achievable dependent upon the RF environment in which the user packages the ROSA.
