(pcb dimensions 65x50mm) a zipped file size 727 kB

 (PCB board real dimensions 65mm X 50mm, this is the version originally presented  in our QEX (ARRL) Magazine July-August 2004 with 74AC86 (squarer) in a dual in line IC package plus FST3125M SOIC package)

I have also   a smaller pcb 51 mm X 36 mm  (unpublished for lack of space in the magazine):  
 a)  h-mode HF mixer all smd (the best in balance, it is always bilateral for both RX-TX), for LO NOT divided.
 


We have also tested:
h-mode HF mixer with a divide by 2 squarer with noise blanker input pulse gate (so a mixer that can be activated as a noise blanker gate in one board)

We have also tested:
c)  sample and hold PRODUCT DETECTOR with a complete audio chain  plus our audio final around TDA2003 IC
d) a board with LSB-USB-CW BFO oscillators for 9 MHz used in our evaluating RX tests
 

Please inquire by e-mail to me, IF REALLY INTERESTED, for availability of pcb templates on a CD  or pcb and cost coverage.
