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 LTC5591 is guaranteed functional over the case operating

temperature range of –40°C to 105°C. (θ

JC

= 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.
