In the block diagram for an RF component, there is a triangle with a slashed zero in it as below:

enter image description here

What is it meant to represent?

    any context to it? – Eugene Sh. Aug 16 '17 at 18:03
  • What component? – Andy aka Aug 16 '17 at 18:04
  • @EugeneSh. It's an RF component but the documentation is confidential and requires an NDA! I wish it was online, really annoying but unfortunately that's all I can show, (think transmitter/ mixers.) I know I've seen it before... – SeanJ Aug 16 '17 at 18:06
  • Well, I would say it is some kind of differential opamp/buffer. Dunno about the zero (phi?) symbol. – Eugene Sh. Aug 16 '17 at 18:10
  • maybe a differential amplifier with 0 dB gain. Used for directional isolation, perhaps. – user57037 Aug 16 '17 at 18:24

    It could be a phase shifter. It does look like a phi. – user57037 Aug 16 '17 at 18:25
  • Well, you could provide at least some context. Like what kind of input it is getting and what kind of out put it is giving – Eugene Sh. Aug 16 '17 at 18:33
  • @EugeneSh. high frequency >70GHz signal going to another triangle that seems to be a phase splitter 0/ 180 outputs and then to an antenna. Unfortunately can't say more and there is literally no key for the block diagram. – SeanJ Aug 16 '17 at 18:40

    @EugeneSh. https://github.com/benishor/rf-symbols perhaps an all pass? – SeanJ Aug 16 '17 at 18:41
  • You are not able to ask the NDA counterparty? They must have someone who can speak to the diagram. – user57037 Aug 17 '17 at 05:11

    @mkeith the NDA counterparty has become very unhelpful, I think they're more used to specialist engineers looking for tweaks rather than a customer trying to understand the tech. My guess is an all pass differential amplifier but it would be nicer to have a reference to back up a guess. – SeanJ Aug 17 '17 at 09:27
