Peregrine Semiconductor has introduced two more UltraCMOS® high-isolation, multi-throw switches – The PE42442 and the PE42452. These switches are successors to the popular PE42451, these SP4T and SP5T switches and include several additional features that support the latest wireless infrastructure demands, including an extended temperature range to 105-degrees Celsius and control logic support of 1.8V and 3V. With the rapid expansion of LTE and soon LTE-A, these high-isolation switches provide a reliable solution for wireless infrastructure applications and enable LTE-infrastructure designs to maximize spectral efficiency and data throughput.
These new switches build on the foundation of the PE42451, the PE42442 and PE42452 include several new features. The temperature support was increased to 105-degrees Celsius for use in rugged conditions, a 1.8V logic control was included to enable lower power consumption and a wider power supply range of 2.3V to 5.5V was employed for maximum design flexibility. Additionally, the insertion loss, isolation and ESD protection on the switch were enhanced. RF engineers will now be able to 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.
Features, Packaging, Pricing and Availability
Covering a frequency range of 450 MHz to 4 GHz, the PE42442 and PE42452 deliver exceptional isolation, linearity invariance over supply, flexible control and unparalleled ESD protection. The PE42442, a SP4T RF switch, is a four-throw version of the PE42452 and offers a 52 dB port-to-port isolation at 2.7 GHz and 61 dB at 900 MHz. The PE42452, a SP5T RF switch, is a pin-compatible upgraded version of the PE42451 and delivers 52 dB isolation at 2.7 GHz and 61 dB at 900 MHz. The 50-ohm absorptive switches have high linearity up to 4 GHz with a more than 55 dBm IIP3. These high-isolation switches deliver ESD protection of 4 kV HBM on all RF pins, enabling high manufacturing reliability.
Offered in a 24-lead, 4x4mm QFN package, samples and volume-production parts are available now. For 10K-quantity orders, the PE42442 is priced at $1.60 each and the PE42452 is $1.92 each. Evaluation kits are also available.
