Peregrine Semiconductor has announced the UltraCMOS® PE426462, PE426482 and PE426412 RF switches that are optimized for applications that demand extreme temperature support. These SP6T, SP8T and SP12T switches deliver excellent performance across a wide temperature range of -55 to +125 degrees Celsius. With high isolation, low insertion loss and a fast RF TRISE/ TFALL time, these absorptive switches boast the high-performance specifications necessary to utilize the full potential of a high-throw count design.
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.
Markets such as radar and harsh industrial have stringent performance requirements, where each component must operate flawlessly in extreme temperature environments. The PE426462, PE426482 and PE426412 are the ideal solutions for the designs that require high reliability, flexibility and top performance.
The PE426462 (SP6T), PE426482 (SP8T) and PE426412 (SP12T) RF switches cover a broad frequency range from 10 MHz to 8 GHz. They have a fast switching time of approximately 200 nanoseconds and a fast RF TRISE/ TFALL time of 100 nanoseconds. The switches provide a high isolation, low insertion loss and high linearity across the entire frequency range and support an extended temperature range from -55 to +125 degrees Celsius.
The PE426462 and PE426482 are offered in a 24-lead 4 x 4 mm QFN package, while the PE426412 is available in a 32-lead 5 x 5 mm QFN package. Samples and evaluation kits are available now. Volume-production parts will be available at the end of March. For 10K-quantity orders, each PE426462 (SP6T) switch is $2.11. Each PE426482 (SP8T) switch is $2.82, and each PE426412 (SP12T) switch is $3.52.
