Note 1: Parts are production tested at TA = +25°C; Min and Max values are guaranteed by design and characterization.
Note 2: BER = 2E-3, Manchester encoded, data rate = 4kbps, IF bandwidth = 350kHz.
Note 3: Input impedance is measured at the LNAIN pin. Note that the impedance includes the 15nH inductive degeneration con-
nected from the LNASRC.
Note 4: Guaranteed by production test.
