+5V SUPPLY AC ELECTRICAL CHARACTERISTICS (continued)

(Typical Application Circuit, VCC = +4.75 to +5.25V, HC mode with each attenuator set for maximum gain, 50MHz ≤ fRF ≤ 1000MHz,

TC = -40°C to +85°C. Typical values are at VCC = +5.0V, HC mode, PIN = -20dBm, fRF = 200MHz, and TC = +25oC, unless otherwise

noted.) (Note 5)
