摘要： RF communications circuitry, which includes a first tunable RF filter and a first RF low noise amplifier (LNA) is disclosed. The first tunable RF filter includes a pair of weakly coupled resonators, and receives and filters a first upstream RF signal to provide a first filtered RF signal. The first RF LNA is coupled to the first tunable RF filter, and receives and amplifies an RF input signal to provide an RF output signal.

摘要： Methods and apparatus that support controlled transmission and directional reception of RTS and/or CTS messages, are described. Controlled transmission may include transmitting a same RTS message multiple times in the same direction and/or transmitting an RTS message with a length that is multiple times longer than a standard RTS message. In an aspect, a receiver may determine spatial directions of a plurality of transmitters including a first transmitter and at least one other transmitter, and may perform a beam sweep in the determined spatial directions for receiving one or more RTS messages. A transmitter may determine that a receiver is to perform a beam sweep in K different spatial directions, and may transmit a same RTS message for a data transmission K times in the same direction or an RTS message with a length approximately K times longer than a standard RTS message, during a duration of the beam sweep.

摘要： A wide-band receiving apparatus used in an FM-FDM type optical image distributing system for transmitting multi-wave and multiple TV signals comprises a circuit for receiving a wide-band input signal containing modified RF signals of two or more different frequency bands and separating the RF signals by the bands; respectively, a first circuit for selecting one of the separated RF signals; a local oscillating circuit for generating a first oscillating signal of a fundamental frequency which is determined based on the frequency range of the selected RF signal; a circuit for producing at least one oscillating signal of a frequency having a predetermined ratio to the fundamental frequency; a second selecting circuit for selecting one of the first oscillating signal and at least one second oscillating signal; a circuit for mixing the selected RF signal with the selected oscillating signal thereby producing an intermediate-frequency signal; and a circuit for demodulating the intermediate-frequency signal.

摘要： The present invention relates to a television tuner capable of receiving television broadcasting, CATV and satellite broadcasting. The television tuner includes a double superheterodyne tuner for receiving television signals, having an up-converter, a down-converter and a coupler for coupling the up-converter and down-converter, and the television tuner also includes a BS second mixer portion and a FM demodulator, for receiving signals from a broadcasting satellite. The double superheterodyne tuner, the BS second mixer portion and the FM demodulator are disposed in a housing, a combination of the up-converter and the BS second mixer portion is desiredly separated from the down-converter, the coupler is disposed in a space between the combination and the down-converter, and the FM demodulator is disposed in the remaining space of the housing.
