Military Microwaves Supplement
The opening session on Tuesday with the CEOs from the big four (Romain Bausch, SES; Daniel Goldberg, Telsat; David McGlade, Intelsat; and Michel de Rosen, Eutelsat) showed that the companies are more optimistic about the market than they were last year. The needs to expand bandwidth and provide communication services to less populated areas are opportunities for satellite providers. The desire for countries to provide Internet access to more of those without access today is another area where satellite can be a solution. While satellite does not have data rates as high as fiber, it can provide coverage much easier to remote areas. But some want to push higher data rates (like 100 Mb/s) over more access. It was said, "Should we get 100% access at 10 Mb/s for everyone or get 100 Mb/s access but not 100% coverage." The cost to do both is probably too high so it would make sense to give everyone access first but people love to talk about very high speed access.
The hot topics at the show were comms on the move, security, lower power consumption (green tech), M2M/SCADA, video standards, hosted payloads, among others. There are forums on various subjects including the MSUA Conference co-located. They moved the event to the Gaylord outside of DC and found it was not large enough to accommodate all the exhibitors this year so it probably will move back to the convention center next year. That is good news for the industry.
MWJ spent two full days on the exhibition floor meeting with various RF and microwave companies displaying their products and services. Below is a summary of what MWJ saw at the show:
There were a few of RF/microwave materials companies present:
Rogers Corp. was showing its 5880LZ laminate that has been formulated to overcome the mechanical and electrical limitations of standard PTFE-based laminate materials. The filled composite material offers the lowest dielectric constant in the industry for a copper-clad PTFE-based laminate with low density that makes it suitable for applications requiring lightweight circuit boards. Microwave Journal recently ran a product feature on this material last Oct. Other materials on hand included the RT/duroid 6202PR and RO3003™ circuit-board laminates.
Isola was featuring its IS680 RF laminate, which has a stable Dk and Df over temperature and frequency. IS680 is not a PTFE-based material rather a "Thermosetting Polymer Alloy" designed to provide improvements in lead free PCB and assembly processes in complex double sided boards (95% copper remaining on both sides) as well as multi-layer printed circuit platforms.
MFG Galileo Composites recently announced that they opened a new manufacturing facility in AL with expanded capabilities and capacity. They can now handle prepregs as they have added oven capacity.
The rest of the companies were components or subsystem RF/microwave suppliers – here is a summary:

Accurate simulation of propagation delays, flat fading, path loss, phase shift and Doppler shifts create realistic, full-duplex path scenarios for closed-loop testing of satellites, ground processing equipment and mobile transceivers. The SLE may be configured with up to four independent channels and operates at a center frequency of 140 MHz (optional 70 MHz, and L, C, S and K-band with optional RF converters). Resolution of static mode is 0.1 ns, dynamic 0.5 ps and Doppler resolution is 0.01 Hz.
CPI announced that ongoing improvements in its C-band Compact High Power Amplifier (CHPA) have resulted in increasingly superior efficiency and lower lifetime cost. Prime power for the 750 W CHPA is only 2.1 kW when running at saturated power. Operation at a linear 325 W output power consumes only 1.75 KVA at linear power.
While Elektrobit did not exhibit, MWJ met with them and saw some impressive satellite devices. They manufacture a cell phone with a satellite phone integrated into the same form as a Blackberry like smart phone. It automatically switches to satellite phone when it is out of range of the cellular service (and outdoors, of course). They also make a device for home satellite data services and dongle type device for satellite connectivity anywhere.
L-3 Communications Electron Technologies has developed a new TWT for use as a high-power microwave amplifier for high-rate transmission of data and video signals from deep space to Earth. The 999HA is a successor to the 999H (a non-space-qualified TWT) operating in the 31.8 - 32.3 GHz frequency band. It has been shown to generate 252 W of CW output power at 62 percent efficiency.
It is back to the DC convention center next year for Satellite 2011 – see you there.
