Peregrine introduces two new SP5T RF switches for next generation high-power LTE public safety and military radios

Peregrine Semiconductor Corp of San Diego, CA, USA, a fabless provider of radio-frequency integrated circuits (RFICs) based on silicon-on-sapphire (SOS), has introduced two new SP5T RF switches for the next generation of high-power LTE public safety and military radios. Peregrine’s UltraCMOS and HaRP technologies allow the new PE42850 and PE42851 switches to achieve 17W of power handling, with high linearity. HaRP technology enables 2fo/3fo harmonic performance of -90dBc into a 1.15:1 VSWR in the PE42850, and -80dBc into a 1.15:1 VSWR in the PE42851. These features, along with a high throw count, make the PE42850 and PE42851 switches ideal for transmission/receive and filter-band switching applications in land mobile radios (LMRs), says the firm.

“The growing complexity of public safety applications and the need to support the challenging 700MHz LTE spectrum are driving the need for high-linearity, small form factor RF switches,” says Mark Schrepferman, director of the communications and industrial product line for Peregrine’s High-Performance Solutions business unit. “As a result, it is increasingly difficult to implement traditional pin-diode switch solutions. The PE42850/51 RF switches offer superior performance, with low power consumption, high linearity, and wide bandwidth in a single, small package.”

The PE42850 and PE42851 switches feature low insertion loss of (RFC-RFx) 0.25dB typical at 520MHz. The switches feature power consumption of 130 microamperes typical. High ESD performance of 1.5kV HBM eases manufacturing and results in longer product life. In addition to SP5T, the new switches can be configured as SP3T devices.

Peregrine has also announced availability of the PE42850 and PE42851 Evaluation Kits.

The PE42850 and PE42851 RF switches are available in a 32-lead, 5mm x 5mm QFN package. Samples and volume-production quantities of the PE42850 are available now. Samples of the PE42851 are available now, with volume-production quantities expected to be available in late June.
