Telecommunications > Receiver Or Analog Modulated Signal Frequency Converter > Signal Selection Based On Frequency (e.g., Tuning) > Frequency Scanning > Multiband MultibandMultiband 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.01/04/07 - 20070004354 - Transit vehicle wireless transmission broadcast system A transit vehicle wireless transmission broadcast system for wirelessly transmitting multimedia content from one transit vehicle to another transit vehicle for broadcast of the multimedia content to passengers traveling in the transit vehicles. Each transit vehicle includes a receiver for receiving the multimedia content or storage device for retrieving the ... 10/12/06 - 20060229039 - Gain boosting for local oscillation distribution circuitry A multi-band integrated circuit radio transceiver comprising receive and transmit radio front end circuit blocks further includes a local oscillation generator for generating a local oscillation for use by the receive and transmit radio front end circuit blocks to down convert received RF signals to baseband or low intermediate frequency ... 08/10/06 - 20060178122 - Interchangeable receive inputs for band and system swappability in communication systems and related methods Interchangeable high band low-noise-amplifiers (LNAs) and low band low-noise-amplifiers (LNAs) and related methods are disclosed that greatly enhance the efficiency of designing handsets for different combinations of frequency bands. The input signals to particular pins on a receiver or transceiver integrated circuit (IC) are swappable such that multiple frequency bands ... 05/04/06 - 20060094381 - Method and system for a synthesizer/local oscillator generator (logen) architecture for a quad-band gsm/gprs radio Methods and systems for processing signals for a multiband radio are disclosed herein. Aspects of the method may comprise dividing an input signal generated by an oscillator used to generate signals for each of a plurality of bands for the multiband radio. A feedback loop reference signal may be generated ... 03/16/06 - 20060057987 - Terminal and associated transducer assembly and method for selectively transducing in at least two frequency bands A terminal is provided for selectively communicating in at least two frequency bands. The terminal includes an antenna transducer including a first port and a second port, where the antenna transducer is capable of selectively transducing first radio signals (e.g., low power radio frequency (LPRF) signals) to and/or from the ... 01/05/06 - 20060003717 - Quadrature subharmonic mixer A quadrature subharmonic mixer comprises a polyphase filter configured to generate quadrature components of a local oscillator (LO) reference signal, a summing and scaling element configured to create additional components of the LO reference signal, and a plurality of mixer elements configured to multiply the quadrature components of the LO ... 11/24/05 - 20050260959 - Dual mode tuning arrangement In a local oscillator for a tuning arrangement for both TV and FM signals there is substantial risk of parasitic oscillation. A special provision is disclosed for effectively reducing this risk. The special provision is a connection of a damping resistor (R1a) for suppressing parsitic oscillations between ground and a ... 08/11/05 - 20050176390 - Slotted multiple band antenna A multiple band antenna has an RF coupling structure (110) and a resonant RF structure (102). The RF coupling structure (110) has an RF connection (116, 118) and an RF coupling end (112, 114). The resonant RF structure (102) is reactively coupled to the RF coupling end (112, 114). The ... 08/04/05 - 20050170798 - Digital video broadcast-terrestrial (dvb-t) receiver interoperable with a gsm transmitter in a non-interfering manner using classmark change procedure A method and a device used for displaying wideband information to a user has a return channel made through a cellular mobile terminal providing interactivity. The device (10) has a first antenna (12) and a second antenna (20), a receiver (14, 16) that is coupled to the first antenna and ... 06/30/05 - 20050143031 - Multi-band receiver A multi-band receiver for receiving an input signal having a frequency situated either in a first band or in a second band. The receiver comprising a mixer for combining an amplified signal having substantially the same frequency as the input signal with a periodical signal generated by a local oscillator. ... ### FreshPatents.com Support |
