AC ELECTRICAL CHARACTERISTICS (continued)
(Typical Operating Circuit with one attenuator connected, V
Typical values are at V
second attenuator is not connected, T
Note 1: Total supply current reduces as R1 and R2 are increased.
Note 2: Operating outside this range for extended periods may affect device reliability. Limit pin input current to 40mA when V
Note 3: All limits include external component losses, unless otherwise noted.
Note 4: Noise figure increases by approximately 1dB for every 1dB of gain reduction.
Note 5: f
Note 6: Switching time is measured from 50% of the control signal to when the RF output settles to ±1dB.
