Peregrine Semiconductor has launched the UltraCMOS PE42525 and PE426525, said to be the industry’s first RF SOI switches to operate up to 60GHz. These two switches set a new standard for RF SOI at microwave frequencies and significantly extend Peregrine’s high frequency portfolio into frequencies previously dominated by gallium-arsenide (GaAs) technology.

Both 60GHz switches deliver exceptional performance in all key RF parameters and have a fast switching speed of only 8 nanoseconds.

The PE42525 is ideal for test-and-measurement equipment, microwave-backhaul solutions and higher frequency switching in 5G systems.

The PE426525 boasts an extended temperature range making it desirable for harsh-environment applications such oil-and-gas exploration and other industrial markets.

Supporting a wide frequency range from 9 kHz to 60 GHz, the PE42525 and PE426525 are single-pole double-throw (SPDT) RF switches.

The two reflective switches deliver an incredibly fast switching speed of 8 nanoseconds and RF TRISE/TFALL time of 4 nanoseconds. Both switches have low power consumption of 450 nanoamperes.

With exceptional performance across all key RF specifications, the switches deliver high port-to-port isolation, low insertion loss, high power handling, high linearity and excellent ESD protection of 2 kV HBM.

At 50GHz, the PE42525 and PE426525 exhibit port-to-port isolation of 38dB and insertion loss of 1.9dB. The PE426525 has an extended temperature range that extends from -55 to +125 degrees Celsius.

The RF switches are available as a flip-chip die with 500 microns bump pitch—the best form factor for high frequency performance as it eliminates performance variations due to wire-bond length.
