pSemi PE42512A

The PE42512 is a HaRP technology-enhanced absorptive SP12T RF switch that supports a frequency range from 9 kHz to 8 GHz. An external VSS pin is available for bypassing the internal negative voltage generator in order for the PE42512 to deliver spur-free performance. It delivers high isolation, low insertion loss, and fast switching time, making this device ideal for filter bank switching and RF signal routing in test and measurement (T&M) and wireless applications up to 8 GHz. No blocking capacitors are required if DC voltage is not present on the RF ports. The PE42512 is manufactured on Peregrine’s UltraCMOS process, a patented advanced form of silicon-on-insulator (SOI) technology. Peregrine’s HaRP technology enhancements deliver high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS.
