    Tuning distributed elements on a PCB

    Thanks, that's illuminating. How would one connect the pads up? With wire?

    Tuning distributed elements on a PCB

    Interesting as I've never come across anything in literature about tuning like this, although maybe I haven't looked hard enough. Could you point me to any general advice on this?

    Tuning distributed elements on a PCB

    Thanks, both. Would it be correct to say that a properly simulated design would generally not need any tuning of distributed elements?

    Tuning distributed elements on a PCB

    With lumped elements it's easy to tune the matching network on a PCB, one can just change the capacitor or inductor for a different one, but I'm wondering what the method is for tuning a PCB that uses distributed elements such as open circuit stubs, for example. Could anyone provide any advice...

    RF Buffer (VHF)

    Thanks for the responses. My only experience of RF amplifiers before this is some power amplifier design. For the circuit configurations mentioned, assuming 50 ohm source and load, would they require matching networks like a power amplifier does? Cheers.

    RF Buffer (VHF)

    The load is reasonably 50 ohm but there could be some slight variation and I'm going to be splitting the signal a number of times so want to isolate the osc output from this. Cheers.

    RF Buffer (VHF)

    Thank you. The waveform is 10 dBm sine from the output of a 50 ohm oscillator and I'll be going in to 50 ohm after the buffer. The supply voltage is 8 V. Cheers.

    RF Buffer (VHF)

    Pardon me, I meant to say buffer and not isolate.

    RF Buffer (VHF)

    I would like to buffer [edited here: i had said isolate] the output of a 100 MHz OCXO. It's a low noise device and I would like to use automotive parts so I'm thinking the best way to do this is to come up with a design using BJTs or FETs. Could you suggest any circuit types? Ordinarily I would...

    Upconverting a 20 GHz signal to 28 GHz

    Thanks, BigBoss. I am using xmicrowave already so that is convenient. My signal generator only goes up to 30 GHz. Would there be any issues with me putting a 24 GHz signal from this through a doubler to give the 48 GHz LO for 48-20=28 GHz? This looks like it would do the trick and seems to have...

    Upconverting a 20 GHz signal to 28 GHz

    Thanks for the responses. I perhaps should have fleshed out my initial post some more. My problem is this: I wish to do end-to-end testing of a pair of up and downcoverters but the output frequency from my upconverter is too low for the downconverter. I will need to preserve the modulation of...

    Upconverting a 20 GHz signal to 28 GHz

    Hello, I need to convert a ~20 GHz signal to ~28 GHz and am looking for some advice. I first thought of using a mixer and taking the sum product from the 20 GHz signal and an LO of 8 GHz. Is this possible? From the searches I have done so far it seems I would struggle to find a mixer with...
