The PE4140 is a high linearity, passive broadband quad MOSFET array with high dynamic range performance capable of operation beyond 6 GHz. This quad array operates with differential signals at all ports (RF, LO, IF), allowing mixers to be built that use LO powers from -7 dBm to +20 dBm. Typical applications range from frequency up/down-conversion to phase detection for cellular/PCS base stations, wireless broadband communications and STB/cable modems. It is offered in a small 6-lead 3 × 3 DFN package.
