NOTES
1Operation down to 0.02 GHz is possible.
2Calculated over the input range of –40 dBm to –10 dBm.
3Mean and standard deviation specifications are in Table I.
4See TPC 9 for plot of Input Impedance vs. Frequency.
5Response time in a closed-loop system will depend upon the filter capacitor (C FLT) used and the response of the variable gain element.
6This parameter is guaranteed but not tested in production. The maximum specified limit on this parameter is the +6 sigma value from characterization.
Specifications subject to change without notice.
