Low cost, but best quality mixer to generate a 2.4 GHz signal for the QO-100 Satellite up link.
We leave it up to you to use any IF frequency between 140 and 500 MHz, all filtering is sufficient to get out a very clean 2.4 GHz signal, this mixer supports all kind of signals, like SSB,CW,FM or any digital modulated.
Your IF - signal may be up to 1 Watt on any frequency, an internal pot allows adjustment of mixer output. LO - power should be 20 mW (13 dBm) for low conversion loss and good IMD.
This mixer will fit to the high gain surplus / UMTS amplifiers available on Ebay and Ham meetings or low cost WLAN - Boosters.
Very low spurious signal, all mixing products are down better than 60 dBc, keeps you free of any trouble with the authorities or other Ham Ops.
For local oscillator (LO) we recommend a PLL - module for high stability or
any other source with 13 dBm with a clean output frequency - will offer a decent PLL - module soon.
The screen shot of output spectrum is no fake, it is real and much better than competitors from far east, sold here on Ebay! Following the HP screen shot are 2 pictures taken with 430 MHz input @ 1 Watt.
To compare quality I've added some screen shots of a competitiors transmit mixer, would you feed such a signal to a power amplifier and antenna?? I don't belive that it is a good idea. Our mixer is desingned for purity of signal, not to underbid every offer!
Technical - Information
The spectrum analyzer shows a mixer driven by 144 MHz @ 1Watt.
