AC ELECTRICAL CHARACTERISTICS The

denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TC = 25°C. VCC = 3.3V, EN = High, PLO = 0dBm, PRF = –6dBm (–6dBm/tone for two-

tone IIP3 tests), unless otherwise noted. Test circuit shown in Figure 1. (Notes 2, 3)

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 LTC5552 is guaranteed functional over the –40°C to 105°C

case temperature range (θJC = 25°C/W).

Note 3: SSB noise figure measurements performed with a small-signal

noise source, bandpass filter and 2dB matching pad on input, with

bandpass filters on LO, and output.
