Direct conversion receiver is a receiver system that is widely used for wireless
communication. Direct conversion receiver replaced the architecture of superheterodyne
receiver. The objectives of my project is to do analysis of IQ Demodulator IC model
LT5516 produced by Linear Technology and also the analysis of direct conversion
receiver system using LT5516 to see the performance of this receiver. The test circuit for
LT5516 is designed using printed circuit board (PCB). Narrowband balun structure is
designed for input of RF signal and LO signal. Air core inductor is used for balun
design. The analysis of LT5516 cannot be done because the connection between the
LT5516 pads and printed circuit board cannot be done so that the test circuit cannot
function without the connection of this LT5516 IC.The LT5516 IC cannot be soldered on
printed circuit board because the size of the IC is too small (4mmx4mm). The soldering
method used is not effective but I still used this method because there are no other
technology in this campus. LT5516 pads are connected to printed circuit board using
wire-wrap as the conductor. Wire-wrap is soldered to LT5516 pads and connected to PCB
pads but lastly IC LT5516 cannot be soldered on PCB because the IC pads are small and
resulted the soldering joint. To solve this problem I decreased the amount of solder but the
wire wrap could not stick on IC pads. Other components are soldered on PCB pads but the
analysis still cannot be done without this IC LT5516. Aluminium box is designed for this
test circuit .The aluminium box is designed to avoid radiation that will effect the output
signal. The calculation for band pass filter and low pass filter are include in this report
even they cannot be applied because the circuit not function and cannot be analyze. The
suggestions also include at the end of the report to ensure that the direct conversion
receiver can function well and can be analyze to see the performance of direct conversion
receiver. |
