Low-priced shortwave receivers often suffer from performance problems that are a direct result of the trade-offs that the manufacturers make to produce a low-cost model. In addition, older receivers ...

The objective of the circuit is to design an amplifier that will be used under radio frequency range with a wideband frequency of 40 MHz. Radio Frequency (RF) – a rate of oscillation or frequency that ...

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 ...

RF amplifiers are electronic devices that accept a varying input signal and produce an output signal that varies in the same way as the input, but that has larger amplitude. RF amplifiers generate a ...

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 ...

This application note demonstrates the use of a low-cost, high-efficiency, 1000W RF power amplifier for 27.12 MHz that runs on a 300V DC supply. To view the application note, click on the URL below.

Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...

Market was valued at USD 7.96 Billion in 2025 and is expected to reach USD 12.57 Billion by 2035, growing at a CAGR of 4.70% ...

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.
