The Conduit of Innovation - Satellite 2016
The SATELLITE Conference and Exhibition attracted satellite end-users representing the entire ecosystem of the satellite community including broadcast, military and government, enterprise, telecommunications, mobility, maritime, commercial and more. The event had 60 sessions in the conference, hundreds of booths on the show floor and a variety of networking opportunities. Pre-show estimates were projected to be more than 13,000 attendees from more than 100 countries for SATELLITE 2016.
Some of the overall satellite market trends are the move toward higher frequencies for more bandwidth (Ka-band), Internet services for remote areas, and small/nano satellites that greatly reduce costs. These trends flow down requirements to RF and microwave companies for more compact, lighter and lower power components and sub-systems. It also affects the design of components such as antennas that need to be smaller in size without losing gain, filters that need to address co-site interference and power amplifiers that need to be more efficient.
We made our way around the exhibition floor and visited the RF/microwave companies displaying products at SATELLITE 2016. Here is a summary of what we found:
ANSYS was featuring several simulation software platforms including EMIT that provides a multi-fidelity approach for predicting RF cosite interference to provide rapid identification and “root-cause” analysis of EMI issues in complex RF environments. EMIT provides a software framework for managing RF system performance data, simulating the impact of EMI on system performance, and mitigating EMI issues. This results in a complete model of the RF environment maintainable over the life of a system.

Noisecom/Booton (WTG) had a great demo that answered the question, “Poor BER… is it Eb/No or signal compression?” with their test setup. It allows companies to test the Satcom’s immunity to noise and interference using a Boonton USB Peak Power Sensor and Noisecom UFX7000A & CNG-EbNo Series Signal to Noise Generator. It showed how to add noise to desired signal to generate BER vs. Eb/No. Noise can act as a jammer and interferer and overload the receiver. The peak power sensor can indicate and measure signal compression due to signal or noise overload. This application targets Satcom engineers testing impact of broadband noise generated by various sources that interferes with the operation of the system. RF-over-fiber system and field engineers testing and troubleshooting the cause of system performance degradation due to signal and noise overload.

R&S was showing off a couple of test solutions and featured the R&S®FSW signal analyzer's excellent dynamic range for phase noise measurements. At 10 kHz offset from the carrier, the R&S®FSW achieves phase noise of –137 dBc (1 Hz) for a 1 GHz carrier and –128 dBc (1 Hz) for a 10 GHz carrier. At 100 Hz offset from the carrier, values of –110 dBc (1 Hz) and –90 dBc (1 Hz) are attained. Featuring a low displayed average noise level (DANL) of typ. –159 dBm (1 Hz) at 2 GHz and –150 dBm (1 Hz) at 25 GHz without using a preamplifier, the R&S®FSW measures spurious emissions quickly and reliably over a wide frequency range. DANL can be further improved by up to 13 dB by means of the analyzer's switch-selected noise cancellation. Users can thus identify even the smallest of spurious emissions that were previously hidden in the noise floor, and effectively optimize transmit systems.
