Note 1: Production tested at T
A
= +25°C. Maximum and minimum limits are guaranteed by design and characterization.
Note 2: Guaranteed by design and characterization.
Note 3: Operation over this frequency range is possible with a matching network tuned to the desired operating frequency.
Note 4: Measured with two-tone test with P
LNAIN
= -25dBm per tone, f1 = 881MHz, f2 = 881.9MHz.
