This cable tv amplifier circuit is a rf amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 Ω cables. The main amplifier si ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two f… ...

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 grandchil… ...

In circuits 1, 2, and 3, the LM386 inputs are connected directly across the tank circuit and use the LM386 as an RF envelope detector. Circuit 4, with its relatively large value coupling capacitor, ...

Hypothetical circuit 1 employs RF gain blocks between the signal source and subsequent signal process is not considered here. Figure 1 is the simplest op amp based gain stage with a 50-Ω input match.

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...

Guerrilla RF, Inc. (OTCQX: GUER) announces that its high-efficiency GRF5509 4-watt power amplifier was selected by Impinj (NASDAQ: PI) for use in their enterprise-grade RAIN RFID reader module ...
