  • Switchable band-pass filter
    Patent number: 9705170
    Abstract: The invention relates to a switchable band-pass filter. In particular, the invention relates to a narrowband switchable band-pass filter over a broad frequency band with two filter elements (including microstripline technology, suitable for use as a cosite filter with a compact structure, which is particularly suitable for efficient mass production and robust in operation. The two filter elements in this context are coupled to one another, on the one hand via a switchable coupling device and, on the other hand, via a direct electromagnetic interaction.

  • Linearization circuit device
    Patent number: 5777777
    Abstract: A linearization circuit device for an electro-optical modulator where an electrical modulation signal is divided by an anti-phase dividing element and is distorted by two distortion elements. The electro-optical modulator has two differential inputs which receive the individual signals.
