The AD8348 broadband quadrature demodulator from Analog Devices lets you perform IF-to-baseband conversions over 50 MHz to 1 GHz for digital-radio architectures (Picture). The 28-lead IC includes a ...
September 29, 2004 Milpitas, CA—Linear Technology Corporation announced the LT5517 quadrature demodulator deigned for 40 to 900-MHz signals. With an IIP3 (Input Third-Order Intercept Point) of ...
I/Q DEMODULATOR ICs (or quadrature demodulators) have been available for some time, but they've generally lacked the high linearity required in some high-performance radio designs. Yet this has ...
The LT5517 incorporates a pair of matched high-linearity mixers with an on-chip quadrature phase generator and splitter. The I and Q signal paths are internally gain matched to 0.03 dB typical, with a ...
NeoPhotonics reportedly announced that it will be introducing the photonic integrated circuit or PIC based Coherent Mixer for 40 and 100 Gbps optical transmission systems at an upcoming conference in ...
Targeting portable applications, the LT5546 IF quadrature demodulator operates on supply voltages down to 1.8V with a typical power consumption of 24 mA. The device accepts input signals from 40 MHz ...
EDAN F15 Series Used in the Study with Its Own IQ Algorithm Proven to Reduce FHR Doubling and Halving Artifacts in Electronic Fetal Heart Rate Monitoring In comparison between IQ demodlation and ...
Harris Corp. has added QAM (quadrature amplitude modulation) capabilities to the company's Videotek DDM-800 digital demodulator. The feature allows demodulation of both 64 QAM and 256 QAM signals in ...
Current extrinsic fiber acoustic sensors face two primary challenges. The first lies in the time-varying initial phase of the interference signal, which arises from environmental vibrations, ...
We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals. We can pull all that together into an educational model for ...
QAM is used to achieve greater spectrum efficiency. This is accomplished by utilizing both the amplitude and phase components to modulate, or alter, the waveform. In this scenario, the QAM waveform ...
