The target here is Doppler cooling AOMs etc, which don't require great linearity or noise, but where high-efficiency is desirable to minimise the lab heat load (e.g. most MCL 2W amps take ~100W). \r\n\r\nRough target is:\r\n\r\n- 19 inch rack module (2U?)\r\n- ~10 channels\r\n- Mains powered\r\n- Target power efficiency close to 50% at saturation\r\n- G=30dB\r\n- P1db > 33dBm\r\n- Cross-talk < -60dB (-80dB preferred)\r\n\r\nIf anyone would potentially be interested in this, then post here and we can discuss further. Otherwise, I'll close this issue and keep this in-house."},"comment":{"url":"https://api.github.com/repos/m-labs/sinara/issues/comments/277002641","html_url":"https://github.com/m-labs/sinara/issues/150#issuecomment-277002641","issue_url":"https://api.github.com/repos/m-labs/sinara/issues/150","id":277002641,"user":{"login":"gkasprow","id":4325054,"avatar_url":"https://avatars.githubusercontent.com/u/4325054?v=3","gravatar_id":"","url":"https://api.github.com/users/gkasprow","html_url":"https://github.com/gkasprow","followers_url":"https://api.github.com/users/gkasprow/followers","following_url":"https://api.github.com/users/gkasprow/following{/other_user}","gists_url":"https://api.github.com/users/gkasprow/gists{/gist_id}","starred_url":"https://api.github.com/users/gkasprow/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gkasprow/subscriptions","organizations_url":"https://api.github.com/users/gkasprow/orgs","repos_url":"https://api.github.com/users/gkasprow/repos","events_url":"https://api.github.com/users/gkasprow/events{/privacy}","received_events_url":"https://api.github.com/users/gkasprow/received_events","type":"User","site_admin":false},"created_at":"2017-02-02T16:14:46Z","updated_at":"2017-02-02T16:14:46Z","body":"One can buy simple Ethernet to I2C or serial bridge and connect temp sensors either with serial or I2C interface that would do all the job\n\n"}}
