Wide bandwidth radio transmitters commonly use analog quadrature modulators (AQMs) to convert complex (I + j*Q) baseband signals to radio frequencies (RF). An AQM consists of a local oscillator (LO) ...

Targeting the aerospace and defense markets, the AFQ100B baseband signal generator delivers a signal source for developing and producing UWB components. Paired with the AFQ-K264 software option, the ...

Palo Alto, Calif.—Test-and-measurement supplier Agilent Technologies Inc. is rolling out a combination of products that tightly integrate digital signal capture of Agilent's logic analyzers with the ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Testing transceiver and converter interfaces requires orthogonal in-phase and quadrature (IQ) analog signals; that is, the phase relationship of the two must be very close to a 90-degree phase offset, ...

With recent rumors and hires suggesting Apple may be planning to build its own custom baseband chips for future iPhones, moving away from off-the-shelf silicon from companies like Qualcomm, one ...
