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 LTC5590 is guaranteed functional over the case operating
temperature range of –40°C to 105°C. (θJC = 7°C/W)
Note 3: SSB Noise Figure measured with a small-signal noise source,
bandpass filter and 6dB matching pad on RF input, bandpass filter and
6dB matching pad on the LO input, and no other RF signals applied.
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.
