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 ...

This circuit in Figure 1 produces the amplitude curve illustrated in Figure 2. 2. Wideband Response for Circuit of Figure 1. The voltage gain of the op amp stage itself is 20, but this is cut in half ...

Buzzwords like Industry 4.0, the internet of things (IoT), mobile computing, and cloud computing can currently be found in many headlines in magazines. The common theme throughout is the development ...

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 ...

We propose a novel flexible jitter-enhanced pulse width modulation(PWM) hardware architecture, which aims to improve the modulation resolution while reducing the requirement of PWM frequency. The ...

Op amps excel at providing many useful and clever solutions to routine or complicated circuit functions. A summing circuit is a perfect example. A summing circuit is typically used in applications ...

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 ...

SummaryRFIC design is a complex “dark art” that limits progress in wireless technologies like 5G, autonomous vehicles, and ...

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.
