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. Downmixer Applications: (Test Circuits Shown in Figures 1 and 2) VCC = 5V, EN = High, TA = 25°C, PRF = –10dBm (–10dBm/tone for two-tone IIP3 tests, Δf = 200kHz), High-Side LO at –5dBm for 45MHz, 140MHz and 450MHz tests, Low-Side LO at –10dBm for 900MHz, 1900MHz and 2450MHz tests, unless otherwise noted.
