MMIC
  1. Fred, Huei and Bob had a phone meeting with Todd Gaier and Charles Laurence on last Friday. Charles Laurence promised to bring up the collaboration issue on the MMIC to the new Chief Scientist of JPL, Huei will follow up and contact with Charles.
  2. Huei received Russell's comment on the InP HEMT design, Huei will ask student to modify it and sent the layout back to AT ASAP. Mal says that this mid-July is the dead line to finish its final design and send to TRW for foundry run.
  3. Regarding the sub-harmonic mixer packaging issue, our aiming is to do it our selves. There are two versions of drawing version with two wave-guide input, Eugene said, and now they are trying to check another design with co-axle input on LO pumping. In the mean time, Eugene is looking for the micro-stripe probe from the market. We hope to get all design and material ready, and bring them to AT for packaging & testing in August.
  4. Huei received a email from Paul Klintworth / TRW, Klintworth expressed TRW's InP MMIC's cannot be re-exported by ASIAA on TRW's license, without the proper re-export authorization from the U.S. dept. of States. He suggests us to contact the TECRO in Washington, D.C. for advice on how to obtain a re-export license. He also concerned about our intentions regarding design efforts, design participants and how it relates to the contemplated agreement, and he wish to have this information from us. Huei will follow up and talk to Fred after this meeting.
