  • RF Switching

    The primary reasons for using vacuum relays in RF applications are their exceptional insulating qualities and their low RF contact resistance-as low as .03 ohms at 30 MHz. This low RF resistance remains stable throughout the service life of the relay because of the advantages provided by the vacuum

    , the resistance of 50 used above reflects that RF systems are matched to 50W. Since RF systems use decibels referenced from 1 mW, the corresponding voltage increase for every 1 mW power increase can be calculated with another form of Ohm's law:. A.H. Systems - RF Related Conversions. 9710 Cozycroft Ave

  • Evaluation of RF Testing

    Transmission Line and Antenna Testing has become a common test of RF network integrity over the past few years. This relatively new testing methodology is a result of new test equipment evolutions and the need to fully understand the integrity of RF networks after installation. While common today

  • RF Probe Calibration

    Introduction: The calibration of RF Field. Probes is a complex process. Characterization is. a more correct term to use than calibration. The. probe must be properly characterized to reflect. how the end user uses his/her probe in their. measurement program. Differences as much as. +/- 6dB can

  • RF Measurement Techniques

    The RF and microwave characteristics commonly used to define the performance of components are typically measured using a vector network analyzer. Since the packages of devices manufactured by Barry Industries, Inc. typically do not have coaxial connectors, the issue of the most appropriate

  • Discrete RF Semiconductors: Alive and Well

    Commercial RF/microwave integrated circuits (RFICs) were establishing a credible toehold. at the time, to the extent that the prevailing conventional wisdom held that discrete. RF semiconductors were on a sure, quick path to obsolescence. My gut reaction told. me that my new assignment had placed

  • Re: Commercial Radio Station Being Picked Up On 447.2375 MHz

    Joshi, perhaps you can explain to us how you would tell the difference between the feed and the broadcast signal, especially since they are identical except for the carrier frequency, power level and a few microseconds of delay as the signal is amped up to broadcast levels. And let's rule out...

  • Re: Surge Arrester

    What kind of transmitter? RF, hardwired, bit rate, signal frequency. Ya think the signal edge has been affected? How? Did you use any test equipment to measure the effects. Can you show a schematic diagram of the transmitter, and receiver circuits. What type of surge arrester, silicon, RTV. What is...

  • Re: RC car circuit

    When your car turns either way, the two motors have an oposite polarity to one another. Find the transistor outputs from the RF decoder that control the motors and XORthem; use the gate output to control a PWM before the DC BUS (e.g. 1=30%, 0=100%). You'll need basic skills in electronics.

  • Re: Wireless remote level control

    How about a laser pointer aimed at a sensor (since you have a clear line of sight)? It potentially could be a lot cheaper than an RF system. If interested, I'll whip out a schematic . . .

  • Re: Sine-wave Light Dimmer

    cnpower I too have an interest in a sine wave controller which would reduce or eliminate RF harmonic interference and hash. May I also have a copy of the circuit schematic you mention? Lonnie...

  • Re: Crystal oscillator problem

    Bread boarding HF is difficult. Typically you can use blank copper clad PC board as a ground plane and then apply or glue strips or pieces of the same PCB to solder components to. We did this type of bread boarding with a lot of RF stuff. We simulate everything in LTSpice (its free from Linear Tech...
