The PE42442 and PE42452, high-isolation, multi-throw switches succeeding the PE42451, have been introduced by Peregrine Semiconductor. These switches feature enhanced operating temperatures up to 105°C maximum, logic control of 1.8V, power supply of 2.3-5.5V, insertion loss, isolation and ESD protection of 4kV HBM.

The PE42442, a SP4T RF switch, is a four-throw version of the PE42452 and offers a 52dB port-to-port isolation at 2.7GHz and 61dB at 900MHz. The PE42452, a SP5T RF switch, is a pin-compatible upgraded version of the PE42451 and delivers 52dB isolation at 2.7GHz and 61dB at 900MHz. As well as this, the 50Ω absorptive switches have linearity up to 4GHz, with more than 55dBm IIP3.

With the rapid expansion of LTE and soon LTE-A, these switches provide a solution for wireless infrastructure applications and enable LTE-infrastructure designs to maximise spectral efficiency and data throughput.

Offered in a 24-lead, 4x4mm QFN package, samples and volume-production parts are available now. For 10,000-quantity orders, the PE42442 is priced at $1.60 and the PE42452 $1.92. Evaluation kits are also available

Kinana Hussain, Senior Marketing Manager, Peregrine, commented: “As the demands of the wireless infrastructure market shift, Peregrine has strategically added key features that help our customers adapt to emerging trends. Peregrine is in a unique position to address many of these demands, largely due to the capabilities of our UltraCMOS technology. RF engineers can now leverage an increased temperature range, lower power consumption and more design flexibility, coupled with key UltraCMOS advantages in reliability, linearity, ESD and consistent RF performance.”
