SIGNAL

OUT

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.

17. Used for experimental purposes. CF ≅ 3pF.

18. C1 is optional (0.001µF → 0.01µF ceramic).

19. R5 is optional and can be utilized to reduce input signal

amplitude and/or balance input conditions. R5 = 500Ω to 1kΩ.
