ALMA Participation of Taiwan
ASIAA joined the ALMA project in 2005 through a collaboration with ALMA-Japan (now ALMA-EA), and in 2008 also by means of a partnership in ALMA-NA. ASIAA thus plays a significant role in ALMA, providing access to this major ground-based facility to the Taiwanese astronomical community.
ASIAA is involved in several projects:

Band-1/MMIC Development
Development of several different MHEMT MMIC LNA designs, 31 - 50GHz GaAs PHEMT cascode mixers, and more.
ASIAA in collaboration with NAOJ
Band-10 Mixer Development
ASIAA has been working on the highest frequency (950 GHz) receiver band (Band 10), in collaboration with Japan, particularly focusing on the mixer design and fabrication.
ASIAA in collaboration with NAOJ
Development of Alternative Laser Synthesizer (ALS)
ASIAA in collaboration with NAOJ has developed an ALS based on a Mach-Zehnder Modulator technology to generate optical Local Oscillator references that can be distributed over long distances of fiber.
lead by ASIAA
Development of LO Reference Test Module (LORTM)
ASIAA has developed a Local Oscillator Reference Test Module (LORTM) for use as a test source at the East Asia Front End Integration Center (EA-FEIC).

Front End Service Vehicle (FESV) (finished 2011)
FESVs are a custom designed trucks packed with the equipment required to transport and service ALMA's temperature-sensitive astronomical equipment without removing a telescope from the working array.
