Highly linear broadband MOSFET array targets medical, test and measurement applications
The PE4141 features low conversion loss of 5.8 dB, high linearity at 25 dBm, and isolation of 44 dB at 100 MHz (LO to IF and RF to IF), making it ideal for low-frequency mixer applications. The array operates with differential signals at all ports (RF, LO, IF), which makes it possible to develop an analog multiplexer that uses LO ports as digital controls, and RF and IF ports as single-ended or differential inputs/outputs. The device also supports up conversion or down conversion in mixer applications.
“The PE4141 is manufactured on Peregrine’s UltraCMOS technology, which not only delivers the high linearity designers expect, but also ensures repeatable performance lot-to-lot,” said Mark Schrepferman, marketing director for Peregrine’s High Performance Solutions (HPS) business unit. “We’ve worked closely with our customers to integrate these important features into a single, low-magnetic package that lowers the impact to the magnetic field near the gradient coil in critical systems such as MRI equipment.”
The PE4141 was designed using a monolithic approach, which not only reduces component count and board area, but also is easier to implement and more reliable compared to discrete, GaAs-based MOSFET arrays.
