Abstract
A radio is described having a synthesizer (17) and a VCO (18). Each of the synthesizer and the VCO has a connection to a ground plane (13) of the radio. The ground plane connection of the VCO has a first capacitor (43) and a further ground connection (40) is provided between the VCO and the synthesizer for providing a common baseband ground for the VCO and the synthesizer, isolated with respect to baseband frequency currents in the ground plane of the radio. The arrangement addresses problems arising in radios having power amplifiers with severe output amplifier variations, such as are found in linear radios.
