TYPICAL PERFORMANCE CHARACTERISTICS
Two-Tone OIP3 vs Tone Power at
Min-Gain
Two-Tone OIP3 vs ROUT, for GMAX
OIP3 vs Frequency for GMAX and
GMIN, POUT = 10dBm
(ROUT = 50Ω) TA = 25°C. VCC = 5V, VCCO = 5V,
ENB = 3V, MODE = 5V, STROBE = 3V, VIH = 2.2V, VIL = 0.6V (Test circuit shown in Figure 16) POUT = 4dBm/tone (2VP-P into 50Ω),
Δf = 200kHz, unless otherwise noted.
