Abstract
A transceiver chipset for digital data transmission has been fabricated using the 25 GHz bipolar Siemens B6HF process. The transmitter IC integrates the complete synthesizer including phase locked loops (PLL), VCOs, frequency doubler, supply voltage regulation and supporting switching functions. Due to the open-loop architecture, the input impedance variation of the switched power amplifier results in frequency deviation of the VCO caused by load pulling. The chipset architecture is suitable for FSK digital mobile radio portable and base stations, especially cordless phone system from 1.6 GHz up to 2.5 GHz.
