摘要
The invention relates to a switchable high-pass filter arrangement which has a lower limiting frequency determining the high-pass filter behavior. The arrangement includes a transistor circuit, which has at least one transistor in a common-gate or common-base connection; a capacitive component in series with the input of the transistor circuit; and a programmable device for setting the operating current of the transistor circuit. In this case, the limiting frequency of the high-pass filter arrangement is switchable by means of the programmable device for setting the operating current of the transistor circuit. This creates a switchable high-pass filter arrangement which does not have any changeover switches in the signal path, is suitable for radiofrequency applications and can be produced in a simple manner. The invention furthermore relates to an optical receiver having a high-pass filter arrangement of this type.
