This FM RF power amplifier has 2 transistors from Philips: BLV10 and BLW87. The 2 rf transistors work in class C and this fm amplifier has a total gain of 21dB (100x) and 55 – 65% efficiency. One low ...

Radio frequency (RF) power amplifiers are all over the place. Some of them can deliver enough RF output power to do biological harm to somebody. Many such amplifiers are solid state, but many others ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

In this blog, we will discuss how Keysight RF Circuit Simulation Professional revamps RF circuit simulation and optimization. Discover how to achieve efficient, accurate designs for even the most ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

Fig. 1: The exciter, with the original RF amplifier section visible at left rear. We don’t need to throw away equipment that is capable of serving for many years to come if it is updated on occasion.

PAC, PNoise, and PXF—allow designers to dissect circuit performance with precision, accurately modeling frequency conversion, ...

If you need an amplifier, [Hans Rosenberg] has some advice. Don’t design your own; grab cheap and tiny RF amplifier modules and put them on a PCB that fits your needs. These are the grandchildren of ...
