Abstract: Amplifiers operating in push-pull are implemented to obviate input baluns and output signal combiners and their attendant losses. Amplifiers having two signal branches that each receive the input signal and have their signal branch outputs connected directly together. Each branch operates during alternate half cycles of the input signal while direct combining of the branch signal outputs produces a composite signal corresponding to the complete input signal. Each branch includes a matching input circuit and a heterojunction bipolar transistor whcih may be configured in either common collector or common emitter arrangement. The transistors are different since one is an NPN while the other is a PNP but they are selected to have similar direct current and radio frequency characteristics.

Abstract: A monolithic diode star mixer incorporating an RF balun and a local oscillator balun in which a center microstrip conductor for each of the baluns is configured between parallel strip transmission lines in a common plane. The RF and local oscillator baluns are positioned in a ground plane such that the baluns are at relative right angles to each other and in which the center microstrips are connected. A center ring conductor enables the diodes associated with the mixer to be connected to the transmission lines and a common connection point. Additionally, an intermediate frequency transmission line is also connected to the conductive ring.

Abstract: A flip-operation mouse device includes a housing, a sliding surface structure, a moving plate, a displacement-detecting device and a control unit. By moving around the moving plate on the upper side of the sliding surface structure and using the displacement-detecting device mounted under the sliding surface structure and on the opposite side relative to the moving plate, the movement and direction of the moving plate and hence the cursor position can be effectively controlled. Furthermore, by moving the moving plate up and down to turn on or off the displacement-detecting device can enable the operation of the moving plate within a smaller space repetitively, so as to effectively extend the maximum equivalent operation area of the moving plate. Therefore, the above-mentioned flip-operation mouse device is able to be operated within a relatively smaller space and can precisely and easily control the cursor position.

Abstract: An inverted mouse apparatus having a movable plate, a main surface structure and a displacement-detecting device is disclosed herein. The attaching element set on the movable plate can be utilized to attach it on a finger that can operate and control the movable plate in three dimensions. The main surface structure is disposed under the movable plate, and both the movable plate and the main surface structure have the adsorptive elements to attach to each other. The displacement-detecting device is set right under the main surface structure to detect the horizontal displacement and direction of the movable plate relative to the main surface structure. Thus an inverted mouse apparatus without the need of the sliding-on-desk or sliding-on-pad operation is provided. The mouse apparatus can not only mimic the movable-type mouse which most people are used to but also control the movement of the cursor more precisely than the stationary-type mouse.

Abstract: A multiple antenna control mechanism for wireless analog communications is disclosed. The control mechanism includes an antenna switch unit, a receiver unit, and a control unit. The antenna switch unit has multiple sets of reception antennas and associated low-noise amplifiers, and a single-pole-multiple-throw RF switch. It receives a wireless by transmitted RF signal that is carrying analog signals. The RF signal is amplified (and down-converted to an intermediate frequency), filtered, and demodulated by the receiver unit. The resulting RF/IF signal is then fed to the control unit for comparison, analysis and identification. When the reception signal quality is poor, the control unit signals the antenna switch unit to change to another reception antenna for maintaining good reception conditions.

Abstract: A broadband monolithic balanced mixer employs a unidirectional active 180.degree. hybrid. The hybrid is fabricated utilizing two active signal splitters, two all pass phase shifting networks and two active signal combiners. The all pass networks provide a controlled phase response while the absolute phase of the network varies with frequency whereby the frequency difference between the two networks remains constant at 180.degree. over a very broad frequency range. Because the phase varies with frequency, the source and load impedance are rendered equal and resistive. Thus the above-described apparatus employs a common source FET with feedback for the signal splitter and a common gate FET for the combiner. Matching networks are used at all four ports of the active hybrid to achieve the desired match over the desired frequency ranges. The outputs of the hybrid are applied to suitable mixer circuits including FET or diode devices.
