Description
The Celeritek CMM2308 is a high dynamic range,
pin-compatible, second source for the TriQuint
®
9132 and the
Mini-Circuits
®
VNA. Providing comparable gain and lower
noise figure than either of the existing standard amplifiers at
25% less drain current, the CMM2308 is an excellent choice
for power sensitive applications, while delivering more design
margin. Packaged in a low-cost surface mount SOIC-8 pack-
age, the CMM2308 will drop into existing designs and offers
improved features and performance.

Test Configuration and Evaluation
Celeritek tests the CMM2308 on an FR4 PC test
board. FR4 was chosen for its low loss characteristics at fre-
quencies up to 2.5 GHz. Plated through hole connections
from the top of the board to the backside ground plane mini-
mizes inductance in the ground connections. These through
hole connections are as close as possible to each ground pin.
For evaluation purposes Celeritek offers a prototype
evaluation board (PB-CMM2308-AJ) for the CMM2308.
Please call the factory or a local representative for more
information.
Handling Precaution
Microwave devices are sensitive to electrostatic dis-
charge. Proper precautions should be taken to avoid ESD
damage.
Physical Dimensions
Ordering Information
The CMM2308 is available in a surface mount SOIC-8 plastic package.
