AD831 Mixer vs ADE-1-24

R-TEK All Messages By This Member #1899 Hi Friends, Its AP2RF Here,? Did anyone try AD831 Mixer Kit for HF Bands?? Any comparison with ADE-1-24 Mixer? Which one has a better Low noise figure,? low conversion loss and IMD?? Kindly share your experience of AD831 as the first mixer in HF. Looking forward to your valued experiences on Linear Mixers. Cheers & 73s / AP2RF / RIFFAD?

g6lbq All Messages By This Member #1901 Hi Riffad I have played a little with the AD831 mixer and in general it is a nice device, I used a couple of the mixers in a dual conversion receiver and they performed okay. Being an active device there is no conversion loss unlike a typical Level 7 diode ring mixer which exhibits 5dB loss. The AD8361 device does have a fairly high noise figure of 10.3dB but the IP3 is quoted as +24dBm which is better than a diode ring mixer @ 15dBm One thing to be aware of is the local oscillator level which must be set correctly, to much drive and you will end up with distortion products. I would certainly buy one of the ready made mixer boards using this device as it is a great module to have to hand. I have built H-Mode mixers and am using one as the 1st mixer stage in my Irwell transceiver and that has an IP3 of 45 to 50dBm so it really is in a different league. Hope this helps Regards Andy (G6LBQ)

If your desire is limited to the "Noise Figure" it is evident that the ADE-1 mixer from Mini-Circuits has an isertion loss of 6db (± 0.5db) over the entire usable band, from LF to UHF, while the 'AD831 declares nothing below 50MHz with a "Noise Figure" of at least 10db around 75MHz, growing up to 17db between 200 and 250 MHz. There are two other important factors in favor of the ADE-1: 1) does not require power supply 2) simply by phase-shifting the mixer with a DC voltage, a direct passage between LO and FR can be obtained (unless the mixer attenuation), also allowing CW transmission by intervening only on the LO frequency. In conclusion, although I have never tried the AD831 directly (but I have tried similar ones like the NE602), I have always been in favor of passive mixers, more versatile and with less intermodulation products than active mixers. 73 de IW4AJR Loris AD831 data sheet ADE-1 data sheet?
