Typical Characteristics (continued)

at TA = 25°C, VS+ = 5 V, Ri = 75 Ω, RL = 150 Ω, maximum gain (1:2-Ω ratio transformer plus 30-dB DVGA gain), f = 5 MHz to

300 MHz, VO converted to single-ended (SE) measurement with transformer, and default current setting (unless otherwise

noted); upon power-up, gain is set to mid-range

f = 200 MHz
