(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have also a smaller pcb 51 mm X 36 mm (unpublished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)

SQUARED
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.
