An Approach to Collector AM Bandwidth of Class E Power Amplier
The Class E amplifiers amplitude modulation mainly relies on the collector DC voltage variations,and the relation between the output signals envelop and the modulating signal is linear in theory,but this is actually impossible.Because of the time-variant property of the load network,the analysis of Class E ampli.er is somehow dif.cult.In this paper,a DC analysis model for Collector AM is proposed from a new viewpoint of equivalent average DC response.The main reasons dividing into 4 parts which will cause the distortion of collector AM are analyzed here.After the discussion,the bandwidth of the AM is obtained,and this model is also validated by some simulation results.
