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 LTC5567 is guaranteed functional over the –40°C to 105°C
case temperature range (θJC = 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: Specified performance includes 4:1 IF transformer and evaluation
PCB losses.
Typical DC Performance Characteristics EN = High, Test circuit shown in Figure 1.
