18 GHz UltraCMOS RF switches improve bandwidth, power handling

September 18, 2014 // By Graham Prophet
Two single-pole, four-way (SP4T) RF switches added to Peregrine's UltraCMOS series feature broad bandwidth, low-frequency power handling and a fast settling time for test-and-measurement equipment

Peregrine Semiconductor's PE42542 and PE42543 18 GHz SP4T broadband RF switches offer test-and-measurement, wireless backhaul and military systems designers broad bandwidth, low-frequency power handling, high ESD protection and a fast settling time. The company says it can provide high-frequency performance levels previously considered unachievable in RF SOI, surpassing the 13 GHz RF SOI barrier and expand its high-frequency portfolio to 18 GHz, with a roadmap to many more high-frequency components.

The SP4T RF switches handle a frequency range between 9 kHz and 18 GHz and offering low-frequency power handling of 10 dBm at 9 kHz. The switches also offer consistent performance across a wide supply range with no drift in insertion loss and phase. Both switches feature 120 µA power-supply-current consumption, which is a fraction of what is required by competing GaAs switches. The PE42542 has a high linearity of 58 dBm IIP3 and 118 dBm IIP2, a fast switching time of 3 µsec and a high ESD rating of 3.5 kV HBM, 150V MM and 500V CDM on all pins. Its fast settling time of 7 µsec eliminates gate lag in test-and-measurement equipment. The PE42543 has a high linearity of 59 dBm IIP3 and 113 dBm IIP2, a switching time of 500 nsec, settling time of 2 µsec and a high ESD rating of 2.5 kV HBM, 150V MM and 250V CDM on all pins. PE42543 are each $18.15 (10,000).
