Communication Circuit Lab (CCL) Facilities
Test and Measurement Equipment
CCL offers a collection of test and measurement equipment that rivals facilities
found in many major corporations. Test and measurement capabilities include:
Additional equipment ranging from 200 MHz oscilloscopes, to accessories
such as power dividers and attenuators are also available for compression
/ intermodulation measurements, noise figure measurements, etc.
RF signal generation to 6 GHz,
Vector network analysis to 6 GHz, and
Spectrum analysis to 22 GHz.
the main application of this equipment is classroom and research use at
the PC board and module levels, the CCL also has capabilities for wafer/chip
level stimulus and measurement. A set of micropositioners with resolutions
approaching 1um (donated by Cascade Microtech), together with 40 GHz coplanar
RF probes allow on-chip 2-port S-parameter measurements to be made.
Electronic Design Automation
Electronic Design Automation (EDA) tools are available in the CCL for use
in circuit and system verification, optimization, and layout. Like the
test equipment described above, the capabilities of this software meets
or exceeds that found in many industry settings.
Through a generous $1.1M donation from Hewlett Packard's EEsof division,
KSU offers students access to the complete Series IV and ADS software suites.
This software is hosted on the department's UNIX network composed of Sun
Sparc 2, Sparc 5, and Sparc Ultra machines and provides system-level, circuit-level,
and electromagnetic simulation as well as microstrip layout tools.
circuits can be fabricated through several methods, depending on frequency
of operation and other requirements. In the undergraduate EECE662 course
(design of communication circuits) students build circuits operating to
100 MHz and above using Ivan Boards. These boards are available
in the Electronics Shop in 2x2 and 2x3 inch formats, and provide a backside
ground plane and a front-side grid on 0.1" centers for SMD component placement
For higher frequencies (to 3 GHz and above), PC boards can be constructed,
either in-house through the department's photo lab in Ward Hall, or via
For special applications, the department also has wire-bonding equipment
and probe-station equipment that can be used for testing unpackaged discrete
components and ICs.
RFIC Design and Fabrication
circuit design is rapidly moving from PC board level development using
standard components, to embedding RF functions into larger systems using
custom Application Specific Integrated Circuits (ASICs). Students at K-State
can develop such ICs by taking courses in both the Communications and Solid-State
Circuits option areas. K-State, like most schools within the country, uses
the MOSIS service for fabrication. MOSIS
provides access to state-of-the-art CMOS technologies ranging from 2 um
to 0.25 um feature sizes, as well as the new
Semiconductor Silicon-on-Sapphire 0.5um technology which is optimized
for RF and mixed-signal applications.
