Design and Construction of a 24 GHz Low Noise Amplifier

24GHz Low Noise Amplifier

 

Tony Long and I designed and built a 24 GHz low noise amplifier for our ECE192 undergraduate independent study project at UCSD.

The amplifier was designed with an early version of Agilent ADS, PCBs were fabricated on Rogers 5880 (Duroid), and we hand built several prototypes on K-connector fixtures that Tony designed. Measured results were consistent with our simulations.

Tony and I won an award for this project at the Eureka! undergraduate research conference in June 2000.

I heard recently that this project is being used as an example of a good EE senior design project at other universities, so I dug up an original copy of the paper we submitted and posted a PDF here.

Sutro Tower now has a website!

Sutro Tower, the 3-pronged behemoth that sits on a hilltop in the geographical center of San Francisco, now has a website.

The coolest part about the site, other than the listing of what radio and TV stations originate from the tower and the status of the DTV conversion, is this graphical representation of what antennas are currently operating.

The lower level auxiliary antennas are activated when the main antennas on top are being serviced, causing all sorts of problems for nearby residents.
