Receivers for the Black Hole Explorer (BHEX) Mission
C. Edward Tong, Kazunori Akiyama, Paul Grimes +6
In this paper, we introduce the receiver architecture for the Black Hole Explorer (BHEX) Mission, designed to reveal the photon ring of black holes. The primary instrument is a dua…
Design and Performance of a Digital Phase Lock Loop for Gunn Oscillators
Todd R. Hunter, Robert Kimberk, Patrick Steve Leiker +2
The digital phase lock loop described in this paper has been in use on the Submillimeter Array (SMA) front-end receivers for over a decade and has been a key element in obtaining a…
A Photonic mm-Wave Local Oscillator
Robert Kimberk, Todd R. Hunter, C. -Y. Edward Tong +1
A photonic millimeter wave local oscillator capable of producing two microwatts of radiated power at 224 GHz has been developed. The device was tested in one antenna of Smithsonian…
Dual frequency 230/690 GHz interferometry at the Submillimeter Array
Todd R. Hunter, John W. Barrett, Raymond Blundell +13
The Submillimeter Array (SMA), a collaboration between the Smithsonian Astrophysical Observatory and the Academica Sinica Institute for Astronomy and Astrophysics of Taiwan, is an…
