Peregrine launches SP6T, SP8T and SP12T RF switches with extended temperature range of -55°C to +125°C

Peregrine Semiconductor Corp of San Diego, CA, USA – a fabless provider of radio-frequency integrated circuits (RFICs) based on silicon-on-insulator (SOI) – has launched the UltraCMOS PE426462, PE426482 and PE426412 high-throw-count, RF switches. Optimized for applications that demand extreme temperature support, the SP6T, SP8T and SP12T switches operate across a wide temperature range of -55°C to +125°C. With high isolation, low insertion loss and a fast RF TRISE/TFALL time, the absorptive switches are said to have specifications necessary to utilize the full potential of a high-throw-count design.

“Markets such as radar and harsh industrial have stringent performance requirements, where each component must operate flawlessly in extreme temperature environments,” says Kinana Hussain, director of marketing. “The PE426462, PE426482 and PE426412 high-throw-count RF switches are an ideal solution for these designs that require high reliability, flexibility and top performance.”

In RF switching, the number of selectable paths corresponds to the throw count of the switch. For example, a SP12T switch like the PE426412 may have up to 12 selectable paths, allowing the design to easily cycle through different sets of functions and multi-function designs. The PE426462, PE426482 and PE426412 switches also feature a logic selection (LS) pin, which provides maximum control logic flexibility.

The PE426462 (SP6T), PE426482 (SP8T) and PE426412 (SP12T) RF switches support an extended temperature range from -55°C to +125°C. Each absorptive high-throw-count switch has a fast switching time of about 200ns and a fast RF TRISE/TFALL time of 100ns. Covering a broad frequency spectrum from 10MHz to 8GHz, the switches have high isolation, low insertion loss and high linearity across the entire frequency range.

The PE426462 and PE426482 are offered in a 24-lead 4mm x 4mm QFN package, while the PE426412 is available in a 32-lead 5mm x 5mm QFN package. Samples and evaluation kits are available now. Volume-production parts will be available at the end of March. For 10,000-unit orders, each PE426462 (SP6T) switch is $2.11, each PE426482 (SP8T) switch is $2.82, and each PE426412 (SP12T) switch is $3.52.
