I wish to use mixer circuit ?as first stage mixer ?, Here is my receiver scheme / Idea ?: ? BPF - RF PRE AMP ( RCA 40673) ?- G6LBQ Ver 2 mixer = 9 MHZ IF to AD603 x 2 ( IF AMP ) - ADE-1 + AD797 ( DEMOD) = NJM 2114 + NJM 4580 ( AF Filters ) = LA4425. ? Kindly also guide if I can have your Mixer PCB ? ?

Hi Riffad I have just updated the files for the Irwell 2nd Mixer stage & Post mixer amplifier and the NEW schematic contains diplexer component values for 9MHz as well as 11.059MHz Please take a look in the files section under 2020 Receive Mixer Stage (DBM) It is late now in the UK and I need to get off to bed but I will look at alternative SMD transistors for the NE46134 and get back to you hopefully tomorrow. For now best regards... Andy (G6LBQ)
