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) ...

Weybridge, UK — Analog Devices has introduced a series of highly integrated RFICs (radio frequency integrated circuits) designed for LTE (long term evolution) and 4th generation (4G) cellular base ...

New programmable, highly integrated modulator, demodulator and dual-mixer simplify design in 3G/4G communications, military/aerospace and instrumentation equipment applications. TAMPA, Fla.--(BUSINESS ...

RF Modulator RCA to Coax - One F type female coax input for connection of antenna , hd tv tuner , satellite set-top / cable box ; And a separate RF coaxial output for connection of TV or RF splitter ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Analog Devices has added to its range of RF chips with a family of five pin-compatible quadrature modulators that together cover the 250MHz to 4GHz frequency range, which covers all mobile standards.

Perhaps the most critical circuit in a broadband wireless system today is the modulator that translates the I and Q baseband signals into RF and upconverts them to the final operating frequency. Such ...

A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...

In his regular browsing on AliExpress, [Ben Jeffrey] came across something he didn’t understand—a $5 fiber optic to RF cable TV adapter. It was excessively cheap, and even more mysteriously, this ...
