  • 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

  • AN-00100 - RF 101: Information for the RF Challenged

    This application note goes to great lengths to. remove the mysteries of RF. The science of RF is unlike any other area of discipline in electronics. Proficient RF design requires. sophisticated test equipment, years of experience,lots of money, and a big smile from Above.Fortunately, while actual

  • Switchmode RF Power Amplifiers

Discussions about RF Schematics
  • 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? lshurtle@juno.com 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...

  • Pasternack Introduces Expanded Lines of In-Stock RF Amplifiers

    Irvine, CA – Pasternack Enterprises, Inc., a leading manufacturer and supplier of RF, microwave and millimeter wave products, has significantly expanded their portfolio of connectorized RF amplifiers including high power amplifiers, high-rel amplifiers, broadband amplifiers, limiting amplifiers, power amplifiers, low noise amplifiers (LNAs), log amplifiers and gain blocks. Pasternack’s broad lines of coaxial amplifiers are employed across the entire spectrum of commercial and military applications including use in radar, electronic warfare, satcom, wireless communications, test lab instrumentation, commercial air traffic control, antenna ranges, telecom infrastructure, sensors and many others. Some of the specialty amplifiers offered in the release, such as limiting amplifiers, are used to protect sensitive microwave receivers by “limiting” excessive input power which could potentially create unwanted distortion or even damage the receiver, while the hi-rel amplifiers are either hermetically sealed or constructed to withstand specific military environmental specifications. Pasternack now offers 107 unique amplifier modules all with varying performance characteristics, giving customers a wide selection of components that meet their application requirements. The new RF amplifiers from Pasternack offer extremely broadband performance depending on the customer’s application requirements. Frequencies across this amplifier line range from DC to 40 GHz, gain levels ranging from 10 dB to 60 dB, P1dB from 2 mW to 100 Watts, noise figures as low as 0.8 dB and gain variation down to ±0.3 dB. The majority of the RF amplifiers offered by Pasternack are equipped with SMA female connectors, while certain high frequency models come with 2.92mm female connectors. All of the cables and components that mate with these amplifiers are also available separately from Pasternack as well. “Our fast growing lines of active components continue to be a focal point of our product development strategy which aims to provide our customers the most comprehensive selection of in-stock and off-the-shelf RF components in the industry,” says Michael Rachlin, Director of Product Management at Pasternack. All of the new connectorized RF amplifiers are in-stock and available to ship from Pasternack today. For detailed specs on these products, please visit www.pasternack.com/pages/Featured_Products/rf-a[...]. About Pasternack A leader in RF products since 1972, Pasternack is an ISO 9001:2008 certified manufacturer and supplier that offers the industry’s largest selection of passive and active RF, microwave and millimeter wave products available for same-day shipping.
