PE4141

Product Description The PE4141 is an ultra-high linearity passive broadband Quad MOSFET array with high dynamic range performance capable of operation up to 1.0 GHz. This quad array operates with differential signals at all ports (RF, LO, IF), allowing an analog multiplexer to be built that uses LO ports as digital controls, RF and IF port as single-ended or differential inputs/outputs. The PE4141 switches the differential input to the differential output at the LO switching rate. Packaged in an 8-lead MSOP package, the PE4141 is ideal for highly magnetic environments such as Magnetic Resonance Imaging (MRI). The PE4141 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
