Appl. No.:

10/902465

Inventors:

Steven Jaffe - Irvine CA, US
Donald McMullin - Laguna Hills CA, US
Ramon Gomez - San Juan Capistrano CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03L 7/00
H03B 21/00
H03B 27/00

US Classification:

331 18, 331 45, 327105, 327106

Abstract:

An apparatus provides a local oscillator signal based on a selected channel of an RF input signal. For example, the apparatus can set a frequency of the local oscillator signal based on the selected channel. Digital circuitry can be used to generate the local oscillator signal. For instance, the digital circuitry can provide a digital representation of the local oscillator signal. A DAC can convert the digital representation to an analog signal. Other circuitry can provide first and second quadrature components of the local oscillator signal, based on the analog signal.

International Classification:

H03G 3/10

US Classification:

330284, 333 81 R, 4552321

Abstract:

An integrated receiver with channel selection and image rejection substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides programable attenuation and a programable gain low noise amplifier. Frequency conversion circuitry advantageously uses LC filters integrated onto the substrate in conjunction with image reject mixers to provide sufficient image frequency rejection. Filter tuning and inductor Q compensation over temperature are performed on chip. The filters utilize multi track spiral inductors. The filters are tuned using local oscillators to tune a substitute filter, and frequency scaling during filter component values to those of the filter being tuned. In conjunction with filtering, frequency planning provides additional image rejection. The advantageous choice of local oscillator signal generation methods on chip is by PLL out of band local oscillation and by direct synthesis for in band local oscillator.

Inventors:

Leonard Dauphinee - Irvine CA, US
Ramon A. Gomez - San Juan Capistrano CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03G 3/00
H03G 3/20

US Classification:

330141, 330278

Abstract:

The present invention provides systems and methods for asymmetrically varying gain in a low noise amplifier. The amplifier includes a first stage amplifier, a plurality of second stage amplifiers coupled to the first stage amplifier, a comparator coupled to one of the second stage amplifiers, and a controller coupled to the comparator, the first stage amplifier, and the plurality of second stage amplifiers. The controller is configured to produce one or more gain control signals to change the gain of one of the first stage amplifier or the plurality of second stage amplifiers at a plurality of asymmetric rates so as to cause the power of the output signal to move toward one of the threshold values of the comparator. The rate of change of the gain is based on conditions including the gain of the first stage amplifier, gain of a second stage amplifier, and the sampled power level.

Abstract:

A receiver to process a RF input signal having a plurality of channels includes a direct down conversion circuit, a demodulation circuit, and a local oscillator circuit. The direct down conversion circuit provides a downconverted signal based on the RF input signal and a local oscillator signal. The demodulation circuit receives the downconverted signal and provides a demodulated signal. The local oscillator circuit sets a frequency of the local oscillator signal based on a selected channel of the plurality of channels.

International Classification:

H03G 3/20

US Classification:

330140, 330147

Abstract:

Satellite set-top boxes (STB) are increasingly being designed with multiple tuners, making them capable of receiving more than one program at a time. In addition, satellite STBs are increasingly being designed with multiple inputs, to permit reception of additional channels that will not fit within the conventional satellite intermediate frequency (IF) band (950-2150 MHz). Often, the STB must route these multiple inputs to the multiple tuners with some form of switching function, to allow each tuner to receive all channel bands. Accordingly, the invention includes an RFIC with two RF inputs and three RF outputs, and a crossbar switch that can route any input to any output. The two inputs are amplified by low-noise amplifier stages.

US Classification:

Abstract:

An apparatus and method is disclosed to calculate the actual received desired channel power from the downstream transmit power of a Cable Modem Termination System (CMTS) when operating at the nominal line voltage and/or at the normal room temperature as per the DOCSIS specification. A Set-top Device produces a Downstream Power Management (DPM) gain measurement signal having a known power level. The Set-top Device embeds the DPM gain measurement signal onto a received downstream multi-channel communication signal. After embedding the DPM gain measurement signal onto the downstream multi-channel communication signal, the Set-top Device downconverts the combined DPM gain measurement signal and downstream multi-channel communication signal to recover one or more communication channels containing information of a broadcast. The Set-top Device measures a power level of a representation of the DPM gain measurement signal embedded within the one or more communication channels containing the information of the broadcast to determine a Set-top Device gain. The Set-top Device measures a power level of the one or more communication channels containing the information of the broadcast.
