  • High frequency circuit device
    Patent number: 5422615
    Abstract: In a high frequency circuit device, inductive circuit elements constituting a matching circuit are constructed of so-called helical coils having fine metal wires wound in a hollow solenoid form, which are disposed inside a package in which a high frequency circuit element such as a surface acoustic wave element or the like is mounted. The high frequency circuit device may be utilized in equipment such as wireless communication equipment for reducing the size as well as providing good high frequency characteristics.

  • Television tuner circuit
    Patent number: 4326295
    Abstract: A television tuner comprises a VHF tuner section and a UHF tuner section and is configured in the two tuned modes of VHF high band and VHF low band between which the input tuning circuit of the VHF tuner section is switched by a diode in response to a source voltage. The television tuner further comprises a bias circuit for biasing said band-switching diode in reverse or forward direction by use of the UHF band source voltage during the receipt of UHF band.
