Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC5569 is guaranteed functional over the –40°C to 105°C
case temperature range (θ
JC
= 8°C/W).
Note 3: SSB Noise Figure measured with a small-signal noise source,
bandpass filter and 2dB matching pad on RF input, and bandpass filter on
the LO input.
Note 4: Channel A to channel B isolation is measured as the relative IF
output power of channel B to channel A, with the RF input signal applied to
channel A. The RF input of channel B is 50Ω terminated, and both mixers
are enabled.
