High Voltage Inverting Charge Pump Produces Low Noise

December 15, 2012

Dual-polarity supplies are commonly needed to operate electronics such as op amps, drivers, or sensors, but there is rarely a dual-polarity supply available at the point of load. The LTC®3260 is an inverting charge pump (inductorless) DC/DC converter with dual low noise LDO regulators that can produce positive and negative supplies from a single wide input (4.5V to 32V) power source. It can switch between high efficiency Burst Mode® operation and low noise constant frequency mode, making it attractive for both portable and noise-sensitive applications.

Small-Signal Intermodulation Distortion in OFDM Transmission Systems

August 13, 2012
A system that utilizes OFDM/OFDMA, such as the E-UTRA (LTE) downlink or the IEEE 802.11a/g and the IEEE 802.16 physical layers, transmits OFDM symbols, each comprising a number of modulated sub-carriers carrying data or pilot symbols, with inter-subcarrier spacing being equal to or an integer multiple of a fixed frequency. The channel bandwidth (B) is determined by the number of 'occupied' (modulated) subcarriers and the subcarrier spacing.

Multicarrier TD-SCMA Feasibility

August 13, 2012
There are several options for the architecture of the transmit signal path. The factors that impact transmit signal elements are introduced, followed by a discussion of the different architectures. Figure 1 shows a direct conversion architecture for an initial point of reference only. Section 6 of 3GPP TS 25.105 describes the transmit signal requirements used throughout this discussion.

Harmonic Mixer Primer: The Gateway to the Millimeter Wave Frontier is Harmonic Mixer Technology

July 17, 2012
The next frequency frontier is the millimeter wave (mm-wave) band, which occupies the 30 GHz to 300 GHz spectrum (wavelengths from 10 to 1 mm). Emerging applications now span radio astronomy, communication, imaging, space research, and homeland security, and are starting to seriously populate this vast spectrum resourse. Market forecast and limited available spectrum suggest that attractive growth is just over the horizon so explorers are naturally migrating to stake their claim in this next frontier.

Small-Signal Intermodulation Distortion in OFDM Transmission Systems

June 13, 2012
The small-signal nonlinear distortion of a system can be described with sufficient accuracy using a third order Volterra expansion of the output in terms of the input. This simple model assumes a memoryless, frequency independent amplifier system, whereby the amplifier characteristics remain constant over the operation bandwidth or, stated equivalently, the operation bandwidth is small compared with the available amplifier system bandwidth....
