Ac electrical characteristics (continued) – Rainbow Electronics MAX2325 User Manual
Page 4
Note 1: Devices are production tested for functionality at frequencies stated; 30 units from 3 independent wafer lots, when one lot
was at the upper process extreme, one lot was nominal, and one lot was at the lower process extreme, were characterized.
The resulting standard deviation therefore includes process variations. Data sheet limits are ±3
σ from the mean.
Note 2: Operation over this frequency range requires the ports to be rematched for the desired operating range. Performance at
various frequencies is indicated by the S-parameter data in Tables 3–7.
Note 3: Specifications are based on R
BIAS
= 20k
Ω. I
CC
for all LNAs (except HGHL) and mixers are inversely proportional to R
RBIAS
.
IIP3 can be traded for I
CC
by selecting other values of R
RBIAS
.
