Featuring integrated local oscillator buffer with bypass mode, UltraCMOS® PE4152 is suited for land-mobile-radio, tactical radio, and cellular infrastructure applications. Quad MOSFET mixer operates from 100–1,000 MHz (RF) and 200–900 MHz (LO). When using LO buffer, linearity is 25 dBm IIP3 and isolation is 30/30 dB LO-RF/IF. In LO bypass mode, linearity is 24 dBm IIP3, and isolation is 60/58 dB LO-RF/IF. Conversion loss is less than 6.6 dB in either LO mode.
