Power Amplifier

Op-Amp's right, not wrong title. I know the op amp is approximately 20 years ago, at age 741/301 series, an easy calculation (gain calculation), affordability, and simplicity of construction makes a very interesting op-amp. So many of the implementation of the op-amp, and even had time to try to build the "op-amp based computer". Almost all can be built with op-amp, except for RF. But that first, reversing the progress of semiconductor technology this condition, a few years back the manufacturers have managed to build an op-amp with a working frequency up to GHz. An article from Texas Instrument by Bruce Carter describes the application of op-amp (THS3202) on the rf circuit. 20dB RF gain op-amp Above circuit provides flat gain of 20dB in the range up to 200MHz.Terminasi input and output impedance is determined by the resistor 49.9Ohm. Strengthening the voltage is determined by resistor 301 Ohm / 5.16 Ohm. Choice of reinforcement could be done as to determi...

RF power amplifier circuit of this work is based on the transistor 2SC1970 and 2N4427. The set output power of 88-108 MHz FM RF Amplifier With 2SC1970 is about 1.3W and the input driver is 30-50mW. RF driver amplifier circuit uses a 2N4427 and its power amplifier using a transistor 2SC1970. At the time of the amplifier circuit tuning FM 88-108 MHz RF Amplifier With 2SC1970 should use the power meter / watt meter or SWR or RF field can also use the meter. RF amplifier circuit can work from the frequency of 88-108 MHz. RF Amplifier Circuit of 88-108 MHz FM RF Amplifier With RF 2SC1970 can radiate far enough. At the time of tuning you should use a 50 Ohm dummy load. For the input signal should be installed to regulate the VR level so as not to over-modulation (30-50mW).
