Peregrine Semiconductor, a fabless provider of high-performance radio-frequency (RF) integrated circuits (ICs), has launched the PE4141 broadband quad MOSFET array core.
The company said the PE4141 provides a combination of high linearity and strong low-frequency performance, monolithic integration and reliability. The array is ideal for mixer and multiplexer functions used in magnetic resonance imaging (MRI), medical instrumentation, and test and measurement applications, said the company.
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).
The array operates with differential signals at all ports (RF, LO, IF), which allows it to develop an analog multiplexer. The device also supports up conversion or down conversion in mixer applications.
The monolithic approach used in the design of Peregrine’s PE4141 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 company claimed.
Peregrine High Performance Solutions business unit. marketing director Mark Schrepferman said 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.
Schrepferman said, "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."
