Abstract
Official abstract text for this publication.
Methods and systems for digitization of broadband analog signals may comprise in a radio frequency (RF) transceiver comprising a diplexer, first and second automatic gain and slope control (ASCS) modules, a combiner, and an analog to digital converter (ADC): receiving an input RF signal comprising at least two signals, splitting the input RF signal in the frequency domain into first and second signals of different frequency utilizing the diplexer, configuring a frequency-dependent gain level for each of the first and second signals utilizing the first and second ASCS modules, combining output signals from the first and second ASCS modules utilizing the combiner, and converting the combined output signals to a digital signal utilizing the ADC. The frequency dependent gain levels of the first and second signals may be configured to enable the ADC to operate with an effective number of bits (ENOB) of approximately 10.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for communication, the method comprising: in a radio frequency (RF) transceiver comprising: a diplexer with a first high pass filter and a first low pass filter, a first automatic gain and slope control (ASCS) module operating over a first frequency range coupled to said first high pass filter at a first output of said diplexer, a second ASCS module operating in a second frequency range coupled to said first low pass filter at a second output o…
