Peregrine Semiconductor Corporation's new SPDT RF switch is for harsh environment and space applications. Manufactured on Peregrine’s UltraCMOS switch is highly resistant to total dose and single event radiation effects, resulting in improved product reliability, as well as stable, and predictable, performance over the life of the mission.
The switch features HaRP technology enhancements for high linearity of 60 dBm IIP3. It is suitable for applications such as RF switch matrices, antenna arrays, and RF communication systems, with an operating frequency up to and including the C-band in commercial satellites, manned spacecraft, and high-altitude aircraft.
As a result of the inherent physical properties of the highly-insulating sapphire substrate, devices manufactured on UltraCMOS technology are naturally immune to radiation-induced latchup.
Further design enhancements ensure exceptionally low levels of performance drift under total dose conditions up to 100 krads (ELDRS free).
The PE95421 switch features low-complexity, single-pin 3.3V CMOS logic control in a single chip. It has low insertion loss ranging from 0.77dB @ 100MHz to 1.38dB @ 8500MHz, and high isolation ranging from 86.5dB @ 100MHz to 27.8dB @ 8500MHz. Low power consumption of 3.3 micro Watts at 3.3V and high ESD tolerance up to 1000V HBM further enhance the ease-of-use of this device.
