2 Stage Chaotic Colpitts Oscillator for the UHF range -  Chaos in the Colpitts oscillator was first reported at the kilohertz frequencies [1].  Later the circuit was investigated in the high frequency (HF: 3 to 30 MHz) range [2, 3].  Chaotic oscillations were demonstrated.  __ 

4 Transistor Transmitter -  This circuit provides an FM modulated signal with an output power of around 500mW.  The input Mic preamp is built around a couple of 2N3904 transistors, audio gain limited by the 5k preset.  The oscillator is a Colpitts stage, frequency of oscillation governed by the tank circuit made from two 5pF capacitors and the inductor __ Designed by Paul K Sherby

A/V Sender -  This small circuit transmitter processes the signs of audio of a sound table or microphone, and the signs of video of a camera, or still the audio signs and video of a DVD, Video-cassette or even it sweats her video plate has an exit of composed video, you can transmit direct of your computer.  Playing them in a channel free from the strip of VHF __ Designed by Toni on Aug 19, 2009

Audio/Video Sender -  This circuit provides you with wireless audio and visual transmission to a TV.  The TV acts as a receiver, eliminating the need to buy a separate monitor.  You can also hook it up to a VCR or CCD Camera, and even set up a remote CCTV security system! __ Contact info @ wzmicro.com

Positive Feedback -  The use of positive feedback is useful for producing oscillators.  The condition for positive feedback is that a portion of the output is combined in phase with the input.  For an amplifier with positive feedback the gain is given by the expression below.   __ Designed by Carl R.  Rod Nave Department of Physics and Astronomy Georgia State University Atlanta, Georgia 30302-4106 EmailRodNave @ gsu.edu

Resonant Frequency of a Colpitts Oscillator -  Using a circuit from the RF schematics section, and the formula from the theory section, you can calculate the resonant frequency for the Colpitts oscillator __ Designed by Andy Collison

RF front-end for triple conversion GPS receiver -  A low-power, 1.57-GHz RF front-end for a global positioning system (GPS) receiver has been designed in a 1.0- m BiCMOS technology.  It consists of a low noise amplifier with 15 dB of gain, a single balanced mixer with 6.3 mS of conversion gm, a Colpitts LC local oscillator, and an emitter coupled logic (ECL) divide-by-eight prescaler.  This front-end has a signal sideband (SSB) noise figure of 8.1 dB and is part of a triple conversion superheterodyne receiver whose IF frequencies are 179, 4.7, and 1.05 MHz.  Low power consumption has been achieved, with 10.5 mA at 3-V supply voltage for the front-end, while the complete receiver is expected to draw about 12 mA __ Designed by Francesco Piazza & Qiuting Huang

Trimless IF VCO: Part 1: Design Considerations -  This App Note explores the design fundamentals needed to implement a trimless, fixed-frequency, IF voltage-controlled oscillator (VCO) and points out the challenges in guaranteeing proper circuit operation.  VCOs are essential components in the architecture of most wireless systems.  In dual-conversion approaches, a fixed-frequencyAPP 711: Feb 05, 2001__ Maxim Integrated
