= 50Ω, unless otherwise
noted. Measurements are performed using Test Circuit A, measuring from 50Ω SMA to 50Ω SMA without de-embedding (Note 4).
Note 1: Stresses beyond those listed under Absolute Maximum Ratings may
cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2: Guaranteed by design and characterization. This parameter is not tested.
Note 3: The LTC6431-15 is guaranteed functional over the case operating
temperature range of –40°C to 85°C.
Note 4: Small-signal parameters S and noise are de-embedded to the package
pins, while large-signal parameters are measured directly from the circuit.
