LTC6431-15
Typical perForMance characTerisTics A-Grade TA = 25°C, VCC = 5V, ZSOURCE = ZLOAD = 50Ω, unless otherwise noted. Measurements are performed using Test Circuit A, measuring from 50Ω SMA to 50Ω SMA without de-embedding (Note 4). OIP3 vs Frequency Over OIP3 vs Frequency OIP3 vs Power Out Over Frequency VCC Voltage
