Test levels: (A) 100% tested at 25°C. Overtemperature limits by characterization and simulation. (B) Limits set by characterization and

simulation. (C) Typical value only for information.

POUT is the signal tone power at the output of the device.

7.5 Electrical Characteristics

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 a transformer, and default current setting (unless otherwise

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