Note 1: Guaranteed by design and characterization.
Note 2: Two tones at 1.9GHz and 1.901GHz at -32dBm per tone
Note 3: Two tones at 1.9GHz and 1.901GHz at -22dBm per tone
Note 4: Mixer operation guaranteed to this frequency. For optimum gain, adjust output match. See the
Typical Operating
Characteristics
for graphs of IFIN and IFOUT Impedance vs. IF Frequency.
Note 5: At this LO drive level the mixer conversion gain is typically 1dB lower than with -10dBm LO drive.
Note 6: Two tones at 400MHz and 401MHz at -32dBm per tone.
Note 7: Transmit mixer output at -17dBm.
Note 8: Calculated from measurements taken at V
GC
= 1.0V and V
GC
= 1.5V.
Note 9: Time from RXEN = low to RXEN = high transition until the combined receive gain is within 1dB of its final value. Measured
with 47pF blocking capacitors on LNAIN and LNAOUT.
Note 10: Time from TXEN = low to TXEN = high transition until the combined transmit gain is within 1dB of its final value. Measured
with 47pF blocking capacitors on PADRIN and PADROUT.
