Abstract:
The invention relates to a Frequency Divider Circuit for dividing an input RF signal to a frequency divided RF signal. The circuit comprises a RF pair, a switching-quad pair coupled in series with a transimpedance amplifier and a double pair of emitter followers. The circuit comprises coupling elements for providing first DC paths to first amplifier paths of the RF pair and for providing second DC paths to second amplifier paths of the series arrangement of the switching-quad pair and the transimpedance amplifier. The first DC paths are independent of the second DC paths. RF connections are provided to couple the first and the second amplifier paths for transferring a signal from the first amplifier paths to the second amplifier paths.
