    pin receptacle. FIGURE 3: rfRXD0420 TOP COPPER. A simple small diameter wire (AWG 24) antenna can be. constructed and inserted into the receptacle. The. length of the wire depends on the frequency. (meters) = c / f (Hertz). where. c = 3x108 = speed of light (meters per second). f = receive frequency
  • Dimming AC Incandescent Lamps Using A PIC10F200
    very simple circuits, not much more than a high-current rheostat (variable resistor) wired in series with the lamp. For low-light conditions, it was adjusted to a high resistance, reducing the current through the lamp filament. For high-light conditions, it was adjusted for a low resistance increasing

  • High Power IR LED Driver Using the PIC16C781/782
    Early infrared (IR) remote control systems employed a simple on-off modulation of an IR LED to transmit the control data between the remote control and the appliance. Unfortunately, while this method was simple to implement, it suffered from both interference and range problems. A warm object
  • Match The Ports Of Differential Devices
    -'). The impedance of the circuit C in Fig. 4 can be calculated by: which can be rewritten as: In this case, circuit D in Fig. 4 is equivalent to circuit C in Fig. 4. When working w. ith transmission-line impedance matching, the simple transformation of the series. element described above will not work. However

    is desired and reverse or zero bias to the isolating arm. This is a. relatively simple approach and has the benefit of being broadband, resulting from. the absence of any frequency selective elements. A consequence of this design. 2. is that power handling of a series connected PIN diode is general
  • Introduction to the BodyCom Technology
    The BodyCom system is a new short-range wireless. connectivity technology that uses the capability of the. human body to transport a few signals that provide. intuitive, simple, and safe communication between two. electronically compatible devices. Communication. between BodyCom system devices
  • Using Multilayer Baluns to Improve ADC Performance (.pdf)
    ideally, the signals on the two differential lines. should be equal and opposite. To this end, a simple ratio of the amplitudes of the signals will. provide a measure of the amplitude balance with 1 or (0 dB if a logarithmic scale is being used). being the ideal value. Similarly, ideally the phase
