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 application note presents the ISL73096RH/ISL73127RH/ISL73128RH transistor arrays and focuses on designing RF amplifiers employing these featured transistor ...

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 ...

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 ...

In modern electronics, enhancing power efficiency while maintaining or even improving performance is critical. Researchers are addressing these challenges through innovative design improvements and ...

Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF) input. When the LO is ...

Modern op amps have much higher operating bandwidths than their predecessors. These new devices are excellent building blocks that can greatly simplify the design and construction of high-bandwidth ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

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.
