Controls Embedded Computing (CWCEC) has introduced a new family of compact,
conduction-cooled rugged ½ ATR-style 3U CompactPCI systems. The MPMC-931x family of Multi-
Platform Mission Computers comes in five standard configurations. Each of these fully developed
system configurations features an integrated 28 VDC power supply and either a DCP-124P SBC Power
Architecture 7448 SBC or a DCP-1201 Intel Core2 Duo SBC. In addition, the MPMC-931x couples these
processing capabilities with a variety of I/O modules to meet specific program requirements such as
graphics, ARINC 429, MIL-STD-1553, Gigabit Ethernet Switching and more.
The MPMC-931x provides high functional density in a small package. As a cold plate cooled
system, the MPMC-931x is designed for reliable operation in harsh environments. Packaged in an
ultra compact form factor and equipped with reliable, industry-leading processing solutions, the MPMC-931x has all the elements required of modern
mission computers in space and/or weight-constrained applications. Optimal system cooling is ensured via thermal transfer between card edges of
its conduction-cooled 3U cPCI cards and the base of the system enclosure. Environmental and EMI sealing is employed for accommodation of a wide
variety of deployed platforms and environments. The MPMC-931x uses advanced packaging techniques to provide advanced processing power in a
rugged enclosure that measures a compact 141.5 cubic inches and a lightweight 4.5 lb, yet is able to operate and survive in external air temperatures of
55°C using a cold plate cooling approach.

3 dB Hybrid Couplers Serve Defense Applications
Narda, an L-3 Communications company, has introduced two
90-degree “mini-hybrid” 3
dB couplers that combine
high isolation with extremely
compact size and the ability
to meet military specifications
for temperature, shock and
vibration. The Model 4031C
operates from 500 MHz to 1 GHz
with isolation of at least 30 dB,
insertion loss of less than 0.2 dB, and maximum VSWR
of 1.25:1. The coupler maintains amplitude balance of +/-0.6
dB and phase balance of 5 degrees. Model 4034C operates from 4 to 8
GHz with isolation of at least 20 dB and insertion loss of less than 0.3 dB,
and maintains amplitude balance of +/-0.6 dB and phase balance of 10
degrees.

Platform Bridges Gap between ATCA and MicroTCA
ATCA is a large footprint form factor and offers extreme computing power, making it ideal for core
network applications, but it is not very flexible or scalable. MicroTCA is a small footprint form factor, ideal
for military Edge-based applications, but does not scale up well. PT is announcing a new product branded as
MONTEREY 8000 that bridges the gap between AdvancedTCA and MicroTCA. This leaves many Aggregationlayer
applications caught in the middle; demanding a mid-size compromise that has plenty of performance
and high-speed bandwidth, but in a cost-effective smaller footprint with flexibility and modularity. PICMG
emerged with the MicroTCA.4 specification, also known as MTCA.4.
The Monterey 8000 platform, based on the Enhanced MicroTCA.4 specification along with highperformance
processing, high-speed IP-based fabric switching, and integrated Linux OS, middleware and
protocols, is highly tuned for next generation networking applications. The platform supports 12 AdvancedMC
modules with Rear Transition Modules. Redundant 10GbE to AMCs is provided with 40GbE aggregated
uplinks. Layer 2/3 Ethernet management is supported and the system provides carrier grade, five-nines
availability with complete redundancy.

Chassis Mount Switching AC/DC Power Supply
Provides 100W
ConTech has announced the
CM100 Series of AC/DC switching
power supplies. The CM100 Series
offers 100 watts of fully regulated
output power in a chassis mount case,
which makes it well suited for many
applications. The easily accessible
terminal block and output voltage
adjustment potentiometer give it
the versatility to be used as a power solution in a large assortment of
applications. The devices have a universal input voltage range of 88 to
264 VAC. The series offers output voltages of 12, 24 and 48 VDC, with
efficiencies up to 84%. Protective features include Short Circuit, Over
Voltage and Overload protection. The metal cage type chassis mount
case is designed for free air convection cooling. The CM100 series is rated
for 3000 VAC isolation, is RoHS compliant, and has UL 60950 approval
pending. Pricing for the CM100 Series is $22.50 each.
