The UltraCMOS PE4152 mixer operates from 100 to 1000 MHz (RF) and 200 to 900 MHz (LO). It delivers excellent linearity, high isolation and low conversion loss in both LO enable and LO bypass modes. When using the 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. The mixer is available in a 20-lead 4 x 4 x 0.85 mm QFN package. The PE4152 is ideal for land-mobile-radio (LMR), tactical radio and cellular infrastructure applications.
