Peregrine Semiconductor has announced the PE42820 and PE42821 single-pole double throw (SPDT) switches for high-power wireless applications that operate up to 2700 MHz. The new switches provide an unprecedented combination of high-power handling and excellent linearity while offering an integrated approach that reduces board area, power consumption and design-in complexity compared to traditional discrete solutions. This combination makes the PE42820/PE42821 ideal for transmit/receive, filter bank and antenna band switching applications in high-power RF systems such as wireless infrastructure devices and land mobile radios for public safety and military environments.
These discrete solutions cannot deliver both the high power handling and high linearity required for broadband frequency support as required for LMR and LTE convergence. In contrast, the PE42820/821 switching ICs offer high 30W power handling while also enabling excellent linearity across the entire 30 MHz to 2.7GHz frequency range. This combination, enabled by Peregrine’s UltraCMOS® technology with HaRP™ enhancements, improves signal clarity and range in high-power RF systems from UHF/VHF through LTE frequency bands.
In addition, Peregrine’s monolithic approach integrates flexible control voltage ranges, which eliminates the need for external bias control circuitry. This reduces the system bill of materials, thereby saving on board space and current consumption, while simplifying design for a more reliable long-term solution. The PE42820/821 switches are supplied in RoHS compliant, 5 x 5 mm 32-lead QFN packages.
Pricing for both devices starts at $11.69 in 10k unit quantifies. Samples and volume-production quantities are available today by contacting Peregrine.
