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 LTC5542 is guaranteed functional over the operating
temperature range from –40°C to 85°C.

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: LO switch isolation is measured at the IF output port at the IF
frequency with fLO1 and fLO2 offset by 2MHz.
