Telecommunications > Transmitter TransmitterTransmitter patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.02/01/07 - 20070026818 - Signal detection arrangement Described is an arrangement including a receiver and an enveloped detection arrangement. The receiver receives radio frequency signals generated according to a predetermined wireless communication protocol. The envelope detection arrangement screens the radio frequency signals for a predetermined signal which utilizes the predetermined wireless communication protocol and has a predetermined ... 01/25/07 - 20070021074 - Am-fm hybrid signal communicated to rfid tags An AM-FM hybrid signal is created which may be used to communicate simultaneously with both RFID tags that receive AM signals and wireless devices that receive FM or PM signals. The AM-FM hybrid signal may be fed back into the system's receiver at the local oscillator in order to recover ... 10/19/06 - 20060234651 - Method and apparatus for hysteresis control A hysteresis control method for a control system includes setting an arbitrary reference value for an existing position of a control width and calculating a difference between a present input value and the arbitrary reference value. A direction of increase/decrease from a control value and an input value variation width ... 09/14/06 - 20060205366 - Polar modulation transmission apparatus and wireless communication apparatus Polar modulation transmission apparatus capable of suppressing power loss of a battery supply line to a high-frequency power amplifier regardless of whether transmission power is high or low is provided. Operation control section (120) performing control in such a manner that a battery voltage (S21) converted as a result of ... 09/14/06 - 20060205365 - Versatile baseband signal input current splitter A current steering mechanism is provided in a radio transmitter (e.g., a multiband radio transmitter) to provide compatibility with a variety of baseband parts. Different proportions of an input signal current (“in”) may be steered to a dummy load (103), a mixer for a first band (106), and a mixer ... 07/13/06 - 20060154620 - Information processing apparatus and method An information processing apparatus for determining whether or not to transmit a predetermined content to a reception apparatus connected to a network, in accordance with a response time taken to respond to a predetermined command, including: reception means receiving a response to a command; measuring means measuring the response time ... 06/22/06 - 20060135089 - Polar modulator and a use thereof A polar modulator has a low AM-AM and AM-PM distortion comprises a phase locked loop. The phase locked loop is designed for outputting a high-frequency signal with a frequency derived from a phase modulation signal at an actuating input of the phase locked loop. A filter device, for suppressing a ... 06/08/06 - 20060121858 - Sigma delta transmitter circuits and transceiver using the same A ΣΔ transmitter that permits setting of a loop filter LF, a charge pump current and other factors to the same conditions even if it is operated in a plurality of frequency bands, therefore allows the number of components to be reduced and at the same time enables the angle ... 06/01/06 - 20060116085 - Vlif transmitter for bluetooth An RF transmitter suitable for Bluetooth transmissions has an IF modulator and an RF modulator, the IF modulator being arranged to use a very-low-IF-frequency, smaller than half the channel bandwidth, such that spurious unwanted modulation components fall in other channels having a channel number within one or two of a ... 03/30/06 - 20060068723 - Linear high powered integrated circuit amplifier A linear high powered integrated circuit amplifier includes a plurality of power amplifiers, balanced integrated circuit coupling, and a combining circuit.
