The amplifying transistor has a base, an emitter and a collector or a gate, a source, and a drain. A capacitor is provided in electrical communication with the transistor. A voltage ... 09/07/06 - 20060199561 - Low temperature co-fired ceramic sub-harmonic mixer A sub harmonic mixer has improved electrical performance in a small package size. The mixer has a low temperature co-fired ceramic substrate. Coupled lines are located within the substrate and connected to an LO port, an RF port and an intermediate frequency port. Three capacitors are formed within the substrate. ... 09/07/06 - 20060199560 - Telemetry system employing dc balanced encoding A telemetry system including a first device having a processor that employs a DC balanced encoding scheme to generate a DC balanced encoded data signal, a modulator for modulating an RF carrier wave by the DC balanced encoded data signal and generating a DC balanced encoded RF modulated data signal ... 07/20/06 - 20060160516 - Pulse shaping optimizer in uwb receiver A receiver for receiving a signal is provided. The receiver comprises a pulse shaper that shapes a received signal using a transfer function, the pulse shaper being adapted to determine a set of coefficients for the transfer function based on the received signal. The receiver also comprises a mixer that ... 06/29/06 - 20060141970 - Three-phase mixer-system Three-phase mixer-systems comprising at least three groups of mixers (1-4,5-8,9-12,30) for frequency translating signals are (basic idea) provided with balancing means (13-21,31) for suppressing certain mixing products with harmonics of the oscillator signal resulting from unbalance (insight). Said three groups of mixers (1-4,5-8,9-12) each comprise a group of switching transistors ... 06/22/06 - 20060135106 - Active mixer with self-adaptive bias feedback An active mixer with self-adaptive bias feedback is described and resolves a poor linearity, inconvenient design of a bias circuit, and other defects of a conventional mixer. The dual self-feedback bias structure according to this invention is used. The active mixer with self-adaptive bias feedback has a power supply, an ... 03/23/06 - 20060063504 - Three-phase mixer-systems Mixer-systems for up/down-converting frequencies comprise many components: in case of balanced quadrature conversion, some parts will show a fourfold repetition (insight). By creating a three-phase mixer-system (10,40), less components will be necessary (basic idea). The sub-signals in the group of sub-signals at the sub-outputs have phase differences being present between ... 03/16/06 - 20060057998 - Frequency mixing apparatus A frequency mixing apparatus is provided. In the frequency mixing apparatus, a PMOS transistor is coupled to an NMOS transistor in a cascode configuration and an LO signal is applied to the bulks of the PMOS and NMOS transistors so that an input signal applied to their gates is mixed ... 03/02/06 - 20060046679 - Flat intermediate if filter for tuners The invention describes an intermediate frequency input circuit (1), which is coupled between output nodes of a frequency mixing circuit (2) and input nodes of an intermediate frequency amplifier circuit (3).
