At the European Microwave Week, Peregrine Semiconductor introduced the industry’s first RF SOI switches that operate up to 60 GHz. The PE42525 and PE426525 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 60 GHz 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.
These switches validate that RF SOI can deliver a high-performing, reliable and fast switching solution at microwave frequencies. Both switches are now part of Peregrine’s high frequency UltraCMOS product portfolio, which includes multiple switches, an image-reject mixer and monolithic phase and amplitude controllers (MPACs). This proprietary technology platform enables these products to reach high frequencies without compromising performance or reliability.
Features, Packaging, Price and Availability
The PE42525 and PE426525 are reflective SPDT RF switches that operate from 9 kHz to 60 GHz. They have high port-to-port isolation, low insertion loss, high power handling, high linearity and excellent ESD protection of 2 kV HBM. At 50 GHz, the PE42525 and PE426525 exhibit port-to-port isolation of 38 dB and an insertion loss of 1.9 dB. The PE426525 has an extended temperature range that extends from -55 to +125 degrees Celsius.
They are available as a flip-chip die with 500 microns bump pitch, which is the best form factor for high frequency performance as it eliminates performance variations due to wire-bond length.
Samples and evaluation kits are available now.
