    摘要: A direct downconversion receiver architecture having a DC loop to remove DC offset from the signal components, a digital variable gain amplifier (DVGA) to provide a range of gains, an automatic gain control (AGC) loop to provide gain control for the DVGA and RF/analog circuitry, and a serial bus interface (SBI) unit to provide controls for the RF/analog circuitry via a serial bus. The DVGA may be advantageously designed and located as described herein. The operating mode of the VGA loop may be selected based on the operating mode of the DC loop, since these two loops interact with one another. The duration of time the DC loop is operated in an acquisition mode may be selected to be inversely proportional to the DC loop bandwidth in the acquisition mode. The controls for some or all of the RF/analog circuitry may be provided via the serial bus.

    摘要: A heat sink mounting assembly includes a socket (90) having first and second side, a retaining clip (10) cooperating with the socket to sandwich a heat sink (70) therebetween. A pair of ears (92) is formed at the first and second sides of the socket. The retaining clip includes a pressing body (11) having first and second ends, a first leg (14) extending from the first end thereof and engaging with one ear, a spring (50) attached to the pressing body, and a second leg (30) attached to the second end thereof and biased by the spring. When the second leg is pressed down toward the socket, the spring biases the second leg upwardly, so that the second leg is resiliently engaged with the other ear. Thus, the heat sink is secured between the socket and the retaining clip.

    摘要: An integrated circuit that performs data demodulation on partially despread symbols includes a despreading unit, a channel compensation unit, and a symbol combiner. The despreading unit despreads input samples and provides despread symbols for a first code channel with a first spreading factor. The channel compensation unit multiplies the despread symbols with channel estimates and provides demodulated symbols. The symbol combiner combines groups of demodulated symbols to obtain recovered data symbols for a second code channel with a second spreading factor that is an integer multiple of the first spreading factor. The channel compensation and symbol combining are dependent on whether or not transmit diversity is used. For a TDM design, despread symbols for multiple first code channels are processed in a TDM manner, one channel at a time, to obtain recovered data symbols for multiple second code channels. The channel compensation unit and symbol combiner can be operated in a pipelined manner.
