NOTE: With one HA-2540 and two low capacitance
switching diodes, signals exceeding 10MHz can be
separated. This circuit is most useful for full wave
rectification, AM detectors or sync generation.
NOTES:
17. Used for experimental purposes. CF 3pF.
18. C1 is optional (0.001F → 0.01F ceramic).
19. R5 is optional and can be utilized to reduce input signal
amplitude and/or balance input conditions. R5 = 500 to 1k.
