Re: [Hackrf-dev] Filter questions

FWIW, minicircuits is a pretty common place to go for filters, lnas, etc. You can get a well characterized unit and be confident it will work the way you expect. If you have enough RF gear to characterize stuff then you can find things on tindie and AliExpress which are cost effective. But

Re: [Hackrf-dev] Filter questions

Thank you for that lead, Dominic. My expertise (such as it is) ends at the ADC, haha. Analog is my bread and butter, so to speak. Brian KE6IYC Sent from my iPhone > On Apr 26, 2018, at 10:45, Dominic Spill wrote: > > On 26 April 2018 at 07:50, Brian Gieryk

[Hackrf-dev] Filter questions

Good morning. What design programs or suppliers are folks using for RF filtering, external to the HackRF? Looking for band pass specifically, multi band, electronically switchable and capable of TX (HackRF output power level only). Thanks in advance for any and all ideas and direction! Brian

Re: [Hackrf-dev] HackRF and Spyverter

Hi, Yes you possibly will damage the spyverter. Though it does have a fairly high level of input attenuation above 65Mhz so it might survive but it certainly won’t do what you are wanting. It is intended to shift a very small level signal up 120Mhz. A better course of action would be an

Re: [Hackrf-dev] Auto-calibration in receiving mode

Hi Dominic, You have been clear. So, to summarise, I have to analyze the signal with the maximum sample rate (20MHz), to include the right value in the graphic and then with the buttons "db/Div" and "Ref level" I must zoom on what I'm interested in. Do you know a block that functions in this way?

Re: [Hackrf-dev] HackRF and Spyverter

anyone knows if Spyverter can be used in oposite direction (to transmit a signal on 120,918Mhz and have it output on 918khz) because HackRF is realy weak on theese low frequencies so if it could put a solid 15dbm below 10Mhz it would be great but I am afraid to damage my Spyverter if I try this
