Abstract :
This letter reports the design and measurements of a SiGe BiCMOS duplexer developed for T/R (transmit/receive) Ka-band SatCom on-the-move user terminals. The IC presented in this work is designed for the integration in a hexa-core chip for dual-band phased array applications. Due to the particular configuration of the chip, the duplexer has four ports: one common port, one input port for the R channel and two output ports for the T channels. The chip size is 570 × 400 μm 2 including the measurements pads. Simulated and measured results demonstrate that the proposed device achieves good performance in both frequency bands in terms of input matching, transmission losses and isolation.
