Supplier Storefronts for Application: SOI - Silicon-On-Insulator

Access the latest products and information from our suppliers

Richardson RFPD employs more RF engineers than any global distributor. By offering deep technical expertise to support the latest products from the leading suppliers in RF & Wireless and Energy Technologies, we are uniquely positioned to help customers meet the challenges of changing markets.

Silicon-on-insulator(SOI) wafer processes utilize a silicon/insulator/silicon substrate instead of an ordinary silicon substrate. This reduces parasitic capacitance which in turn improves RF performance. Sapphire is the preferred insulator for RF applications, and this type of SOI is commonly referred to as silicon-on-sapphire(SOS). Our offering of SOI products are integrated circuits from Peregrine, the RF leader in SOI/SOS with their UltraCMOS® process. Peregrine’s UltraCMOS is proven and reliable, with over one billion ICs shipped to date for cellular infrastructure, CATV, and A&D applications. With product offerings ranging from DC to 13.5 GHz, performance advantages of SOI include:

  • Better Isolation – up to 90 dB
  • Higher Linearity – up to +70 dBm Input IP3
  • Lower Insertion Loss – lower than 0.3 dB
  • Fast – as low as 0.3 microsecond switch speeds
  • High ESD – up to 2 kV HBM (Human Body Model)

SOI historically has been used to make RF switches, digital step attenuators (DSAs), and phase lock loops (PLLs). The newest RF products offered on SOI are digitally tunable capacitors (DTCs), which offer exciting design possibilities in applications such as A&D and cellular.
