Posted: Mon Jul 19, 2004 11:50 am 
Greetings all,

I'm kinda new in this area, and was given a task to intergrate the RF front-end digital Beamformer circuit. my question is how do i do that, what are the paramters that i should take consider of? does the word intergrate means i have to convert the signal in frequency domain into time domain? is there any book reference that i can refer to regarding beamforming network? I just need to know how to start with this project? Many thanks.

cheers

ElfaDija

Beamforming is usually done with an Array or antennas sperated by Quater wavelength and applying amplitude and phase shifts to the signal so that the directivity of the array can be rotated. You can do complex multiplications in digital domain to achieve this.

Greetings Elfa:

I just picked up the August 2004 edition of Microwave Journal and see there is a major feature article on beam-forming antennas that you might be interested in reading.

Here's a link to the article, but you might need to sign in to access it:

check out
Digital beamforming in Wireless Communications
John Litva and Titus Kwok-Yeung Lo
Im currently doing a project on it as well.

Basically try reading up on
Adaptive beamforming networks
since u need smart arrays and a digital beamforming network.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
