Title:
【発明の名称】出力増幅器
Document Type and Number:
Japanese Patent JP2933317
Kind Code:
B2
Abstract:
An output amplifier for pulse generators comprises a first bipolar transistor amplifier stage (4) and a second gallium arsenide field-effect (GaAs FET) transistor stage (5). The GaAs FET transistor amplifier stage (5) is used to generate high output swing and fast transition times over a wide frequency band, whereas the bipolar transistor amplifier stage (4) provides high gain and compensation of the GaAs anomalies.
