MICROWAVE PROJECT
Compact Microwave circuits using LTCC
Weibel Scientific A/S is a world-leading Doppler radar manufacturer for the aerospace, defense and
forensic science community.
Problem
Highly advanced radars need multiple transmitters and
receivers. If the amount of transmitters and receivers is to
increase manifold without the antenna size to increase
drastically as well, miniaturization of the microwave circuits is
needed. One solution is to make compact microwave circuits
using low temperature cofired ceramics (LTCC), in
combination with bare die monolithic microwave integrated
circuits (MMIC).
Challenge
The project goal is to design the X-band receiver or parts of
the receiver using LTCC technology, eg. Filters, splitters, LNA
or mixer circuits.
The student should design and simulate the circuits using
appropriate software. When the circuits meets the design
criteria, the student is to manufacture and test the circuits
using the thick film lab at DTU.
In addition, if the use of active devices is needed, proper
encapsulation should be considered.
