ELECTRICAL CHARACTERISTICS (continued)
( Typical Application Circuit , all RF inputs and outputs are referenced to 50Ω, V
otherwise noted. Typical values are at V
Note 1: Supply current, output power, and efficiency are greatly dependent on board layout and PAOUT match.
Note 2: Production tested at T
Note 3: 50% duty cycle at 10kbps with Manchester coding.
Note 4: Guaranteed by design and characterization, not production tested.
Note 5: PA output is turned on in test mode by V
Note 6: PA output is turned off in test mode by V
Note 7: Wait time: t
Note 8: Generally limited by PCB layout.
Note 9: V
