Note 1: Limits over temperature guaranteed by correlation to worst-case temperature testing.
Note 2: This is the recommended operating frequency range. Operation outside this frequency range is possible but has not been
Note 3: Specifications are corrected for board losses (0.25dB at input, 0.25dB at output).
Note 4: Guaranteed by design and characterization.
Note 5: Input IP3 measured with two tones, f
Note 6: Input IP3 measured with two tones, f
Note 7: Specifications are corrected for board losses (0.25dB at input).
Note 8: Time from when GAIN changes state to when output power reaches 1dB of its final value.
Note 9: Time from when SHDN changes state to when output power reaches 1dB of its final value.
