(Note 6)
CONDITIONS
Note 6: Guaranteed by design and characterization.
Note 7: Image rejection typically falls to 30dBc at the frequency extremes.
Note 8: Refer to the Typical Operating Characteristics for a plot showing Receiver Gain vs. LNAGAIN Voltage, Input IP3 vs.
LNAGAIN Voltage, and Noise Figure vs. LNAGAIN Voltage.
Note 9: Two tones at P
RXIN
= -45dBm each, f1 = 915.0MHz and f2 = 915.2MHz.
Note 10: Time delay from V
RXON
= 0.45V to V
RXON
= 2.4V transition to the time the output envelope reaches 90% of its final value.
Note 11: Output power typically falls to -10dBm at the frequency extremes.
Note 12: Two tones at V
TXIN
= 125mVp-p, f1 = 1.0MHz, and f2 = 1.2MHz.
Note 13: Time delay from V
TXON
= 0.45V to V
TXON
= 2.4V transition to the time the output envelope reaches 90% of its final value.
Note 14: Using tank components L3 = 5.0nH (Coilcraft A02T), C2 = C3 = C26 = 3.3pF, R6 = R7 = 10Ω.
Note 15: This approximates a typical application in which TXOUT is followed by an external PA and a T/R switch with finite isolation.
Note 16: Relative to the rising edge of PREOUT.
