1 Watt 2.3 GHz RF Amplifier using a MRF2001 -  Simplicity and repeatability are featured in this 1-watt S-band amplifier design.The design uses an MRF2001 transistor as a common base, Class C Amplifier.The amplifier delivers 1-watt output… [electronic design by Michael Micili]

 

1 Watt 2.45 GHz Linear Amplifier -  schematic only, no description included… [Green Bay Professional Packet Radio]

 

1 Watt Audio Amplifier Project (Using the TAA300) -  I built this audio amplifier with the TAA 300 Integrated Circuit (IC) to have on the work bench an independent amplifier to test audio signals coming from radio receivers or audio oscillators. It is an excellent amplifier to drive an eight ohm loudspeaker. You can use it, for example, as an audio amplifier for the FM one transistor receiver known as the Radio Shack Special and/or the TDA 7000 FM receiver; also to test the workings of a pulse oscillator or any other kind of audio oscillators.… [braincambre500 AT yahoo.com]

1.5kW Power Amplifier -  Just the thing for those for whom no amount of power is enough  … [Rod Elliott (ESP)]

 

10 watt HF 17 meterband amplifier -  This project and your efforts will provide you with a 0.55.3 watt input to easily 10 watt output. The two linear amplifiers are ment for use with QRP SSB/CW/FM/AM transmitters on the amateur bands 15 and 17 meters can be powered from a 12 volt DC supply. The design is a good balance between output power, physical size. The completed amplifier will reward the builder with a clean, more powerful output signal for a QRP rig when radio conditions become marginal. It has a RF-sensing circuit (Q2) wich allows the amplifier to switch on automatically when transmitting. This project uses a "classic" RF transistor. MOSFET power amplifiers are discussed and build in the near future on this website.… [by Guy Roels ON6MU]

 

100 Watt Amp Circuit -  Guitar amplifiers are always an interesting challenge. The tone controls, gain and overload characteristics are very individual, and the ideal combination varies from one guitarist to the next, and from one guitar to the next. There is no amp that satisfies everyone's requirements, and this offering is not expected to be an exception… [Rod Elliott (ESP)]

 

100 Watt RMS Amplifier -  This is a100-Watt basic power amp that was designed to be (relatively) easy to build at a reasonable cost. It has better performance (read: musical quality) than  standard STK module amps that are used in practically every mass market…

 

10W amplifier using TDA2003 -  Here is the circuit diagram of a 10W audio amplifier using the popular TDA2003 IC from SGS Thomson. The IC can easily deliver 10W to a 4 Ohms load at 18V DC supply voltage. The IC can be also operated from 12V and that makes it applicable in car audio systems…

12 Volt powered, 4x15 Watt Audio Amplifier -  Using car audio chips and intended for installation inside a computer.… [Manfred Mornhinweg]

 

15dB UHF TV Antenna Booster -  This is an UHF band TV antenna preamplifier circuit With 15dB gain to build easily. It is formed based on BF180 UHF Transistor. The first stage is an band pass filter constructed by the C1, CV1, L1, L4, C7 and C3, the second stage is a base-common…

 

16 Watt Amplifier -  this circuit provides 16 watts of amplification. it is built using two LM383 power audio amplifiers. use suitable heat sinks with the ic's… [Andy Wilson's site]

 

18W Audio Amplifier -  High Quality very simple unit -- No need for a preamplifier… [by IQ Technologies Industry, unless otherwise noted online]
