Crystal Radio Circuits techlib Simple Crystal Radio. The crystal radio gets its name from the galena crystal (lead sulfide) used to rectify the signals. A "cat's whisker" wire contact was moved about the surface of the crystal until a diode junction was formed. RF Diode Design Guide SKYWORKS WWW.SKYWORKSINC.COM 7 The receiver protector function is performed by a specially processed PIN diode, known as a limiter diode. The PIN limiter Cell Phone Detector Circuit | Mobile Phone Tracking System ... Basic Principle of Mobile Phone Detector Circuit. The basic principle behind the Cell Phone Detector circuits is to detect the RF Signals. In the Schottky diode circuit, the Schottky Diode is used to detect the cell phone signal as they have a unique property of being able to rectify low frequency signals, with low noise rate. RF connector A coaxial RF connector (radio frequency connector) is an electrical connector designed to work at radio frequencies in the multi megahertz range.

NEDI Technology Co., Ltd (NEDITEK) is the trading company adheres to NEDI. NEDI is one of the leading research institutes in R&D and production of electronic devices and components. A radiation detector with a solid state PIN diode sensor ... I saw a cool app note from Maxim that described a gamma photon detector which used a regular PIN diode as a sensor. The actual circuit looked simple enough so I decided build it, you can never have too many measurement instruments right? New Lightning Detector for the Beginner techlib New Lightning Detector (Also see magnetic antenna version, op amp version and pound Transistor version) Also: Original Lightning Detector Page Diode A diode is a two terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. Circuit Zone Electronic Projects, Electronic ... This FM radio receiver circuit is very simple to build and is powered by just a single 1.5V battery cell. Receiver consists of a regenerative rf stage, TR1, followed by a two of three stage audio amplifier, TR2 to TR4. Dictionary of Electronic Diode Terms interfacebus Diode Detector.

TA2111N F FN 1 2002 03 05 TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA2111N,TA2111F,TA2111FN 3 V AM FM 1 Chip Tuner IC TA2111N F FN are AM FM 1 chip tuner ICs, which are designed Two Diode Odd Order Frequency Multipliers Two Diode Odd Order Frequency Multipliers. It is often necessary to multiply the frequency of low noise oscillators without significantly degrading the phase noise beyond the theoretical 20 log (N). Circuit Improvements for the TS 440S somis.org Circuit Improvements for the TS 440S by Richard L. Measures, AG6K Updated December, 2002. PROBLEM: Distortion level in SSB transmitted signal not acceptable. High Performance Regenerative Receiver circuit's stability for CW and SSB reception. C7 is the throttle capacitor REGEN ADJUST control. As C7's capacitance is increased, more RF energy is coupled PIR Motion Detector Electronics DIY Along with the pyroelectic sensor is a bunch of supporting circuitry, resistors and capacitors. It seems that most small hobbyist sensors use the BISS0001 ("Micro Power PIR Motion Detector IC"), undoubtedly a very inexpensive chip. DIRECTION SENSING INFRARED MOTION DETECTOR MANUAL Glolab GLDIR _____ Description The GLDIR direction sensing motion detector is 1.7 X 2.4 inches with circuit components on one side and a pyroelectric infrared sensor on the other side.
