X-Fab has extended its IP offering to include RF building blocks for its 0.6 µm BiCMOS technology. This XB06 process technology is dedicated for the design of radio-frequency ICs for operating frequencies up to 1 GHz. The building blocks are optimized for the 868 MHz ISM band. The XB06 design kit contains RF-passive devices such as inductors, varactors and MIM-capacitors. It also includes RF-optimized bipolar transistors. X-FAB developed and also is making available an additional analog library containing typical RF building blocks (LNA, LC-VCO, Prescaler), fully characterized and documented to facilitate the design of RF-ASICs. To allow a broad range of applications, the RF building blocks are functional in a wide range of supply voltage from 2.5 V to 5.5 V.
