3 / 16 page LT5527 3 5527fa 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: 450MHz, 900MHz and 3500MHz performance measured with external LO and RF matching. See Figure 1 and Applications Information. AC ELECTRICAL CHARACTERISTICS Test circuit shown in Figure 1.

Note 4: SSB Noise Figure measurements performed with a small-signal noise source and bandpass filter on RF input, and no other RF signal applied. Standard Downmixer Application: VCC = 5V, EN = High, TA = 25°C, PRF = –5dBm (–5dBm/tone for 2-tone IIP3 tests, Δf = 1MHz), fLO = fRF – fIF, PLO = –3dBm (0dBm for 450MHz and 900MHz tests), IF output measured at 240MHz, unless otherwise noted.
