The RF signal transmitted must carry some information ... consider the control characteristics of a vacuum tube amplifier. Figure 1 shows the dynamic characteristics of a triode tube amplifier. The ...

Figure 3 Solid-state RF power amplifier, corrected Figure 4 Vacuum tube RF power amplifier, corrected In these two new schematics, a radio frequency choke (RFC) has been added across the RF output. If ...

Looking at the tubes available, it’s clear that if you are searching for an obscure 1050s small-signal RF tube you’ll be out of luck; these are mostly audio amplifier parts, double triodes ...

the amplitude of the RF carrier will vary with the audio signal, completing the amplitude modulation. In the tube circuit, the amplifiers operate class B for the modulator and class C for the RF ...

An RF power amplifier is a device designed to convert a low power radio frequency signal into a higher power radio frequency signal. Moreover, based on several parameters RF power amplifiers are ...

Vacuum tube amplifiers just won’t go away ... And even my ham gear is solid state although one can still buy RF power amps with multiple kinds of vacuum tubes. It is hard to beat them for ...

Microchip Technology Inc has added the new SST12LP17E and SST12LP18E devices to its RF power amplifier portfolio. The SST12LP17E require only one DC bypass capacitor to achieve optimum performance.

To support the requirements of the new Data over Cable Service Interface specification (:DOCSIS) 3.1, RF Micro Devices Inc. (RFMD) recently unveiled its first power doubler amplifier in a multi ...

SpacePath Communications, a division of ETL Systems, that provides high-performance satellite uplink amplifiers for the global SATCOM market, has introduced its highest power stand-alone C-band ...

Instrumentation amplifiers serve in a variety of applications that need to extract a weak differential signal from large common-mode noise or interference. However, designers often overlook the ...
