Peregrine Semiconductor Corporation has released its newest UltraCMOS™ RFIC, the 50-ohm PE4150 quad MOSFET core device, suited for mixer designs requiring low conversion loss and high linearity such as portable radios operating in bands from UHF through 900 MHz. The PE4150 is a highly linear passive mixer that incorporates an integrated LO amplifier with very high LO isolation. This allows for LO drive levels as low as -10 dBm producing IIP3 values typically associated with 15 dBm LO drive. The PE4150 operates with differential signals at the RF and IF ports and the integrated LO buffer amplifier drives the mixer core. The device can be used as an up converting or a down converting mixer. The PE4150 is manufactured on the company’s UltraCMOS™ process, a patented variation of silicon-on­insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS. The PE4150 mixer, packaged in a 4x4 mm 20-lead QFN.
