A hybrid integrated circuit device having high mount reliability includes a module substrate which is a ceramic wiring substrate, a plurality of electronic component parts laid out on the main surface of the module substrate, a plurality of electrode terminals laid out on the rear surface of the module substrate, and a cap which is fixed to the module substrate to cover the main surface of the module substrate. The electrode terminals include ones which are aligned along the edges of the module substrate and power voltage supply terminals which are located inner than these electrode terminals. The electrode terminals aligned along the substrate edges are coated, at least in their portions close to the substrate edge, with a protection film having a thickness of several tens micrometers or less. Connection reinforcing terminals consist of a plurality of divided terminals which are independent of each other, and are ground terminals.

Hybrid integrated circuit device, and method for fabricating the same, and electronic device

A technique is provided for achieving reduction in size of an electronic device with a power amplifier circuit, while enhancing the performance of the electronic device. An RF power module for a mobile communication device includes first and second semiconductor chips, a passive component, and first and second integrated passive components, which are mounted over a wiring board. In the first semiconductor chip, MISFET elements constituting power amplifier circuits for the GSM 900 and for the DCS 1800 are formed, and a control circuit is also formed. In the first integrated passive component, a low pass filter circuit for the GSM 900 is formed, and in the second integrated passive component, a low pass filter circuit for the DCS 1800 is formed. In the second semiconductor chip, antenna switch circuits for the GSM 900 and DCS 1800 are formed. Over the upper surface of the wiring board, the second semiconductor chip is disposed next to the first semiconductor chip between the integrated passive components.

RF power module

A game machine capable of causing a player to pay attention to a game title image. The game machine comprises a default game title image storing section (), an optional game title image storing section (), an operation input section (), a selection section (), and a display section (). When no game operation input is made within a predetermined time after a predetermined timing, the selection section () selects a default game title image so that the default game title image is displayed by the display section (). When any game operation input is made within a predetermined time, on the other hand, either a default or optional game title image is displayed by the display section () depending on whether the content of the game operation input satisfies a predetermined condition.

Game machine, game title display control method and program

Disclosed herein is a high frequency power amplifier system having a transistor comprised of a first electrode, a second electrode and a control electrode and for controlling current which flows between the first electrode and the second electrode by applying a potential to the control electrode, and a resistance type potential divider circuit for determining a dc bias potential applied to the control electrode of the transistor, and wherein an input signal is inputted to the control electrode, an output signal is outputted from the first electrode and a control signal is inputted to the resistance type potential divider circuit. One resistor of the resistance type potential divider circuit is comprised of a temperature compensating resistor whose resistance value varies linearly, so that a temperature characteristic of an idle current defined as an output when the control signal is not inputted, assumes a negative temperature characteristic.
