Semiconductor offers linear broadband MOSFET array

Paul Boughton
Peregrine Semiconductor Corporation, a fabless provider of high-performance radio-frequency (RF) integrated circuits (ICs), today announced the PE4141 broadband quad MOSFET array core.

The PE4141 leverages Peregrine’s UltraCMOS technology to deliver a combination of high linearity, strong low-frequency performance, monolithic integration and reliability that is suitable for mixer and multiplexer functions used in magnetic resonance imaging (MRI), medical instrumentation, and test and measurement applications.
The PE4141 features low conversion loss of 5.8dB, high linearity at 25dBm, and isolation of 44dB at 100MHz (LO to IF and RF to IF), making it ideal for low-frequency mixer applications. The PE4141 operates with differential signals at all ports (RF, LO, IF), which makes it possible to develop an analogue 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.”
Peregrine’s 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.
The PE4141 is available now in volume production, supplied in the 8-lead MSOP package priced at $7.00 in 10K quantity orders.  Samples are available to qualified customers through Peregrine’s global sales representatives and its worldwide distribution partners.
