Large Platform Co-Site Interference Mitigation

Analyzing co-site interference using electromagnetics simulation solutions requires:

  • Accurate determination of the coupling between antennas over a broad frequency range
  • Evaluation of the impact of non-linear electronic effects

This white paper describes how to analyze co-site interference on large multi-antenna platforms, modify proposed configurations, and easily eliminate co-site interference problems.

Cost-effective Front-end Components for X- and Ku-band Phased Array RADAR

This paper looks at common system architectures for short- to medium-range AESA radars, with a focus on the front-end components used to enhance system performance. These components include the power amplifier (PA) for transmit, the low-noise amplifier (LNA) for receive, and the transmit-receive switch to connect the antenna to the electronics. Key features include the different power levels, frequency bands, and compact size required to use these systems in urban areas.

Stop the Clock, How Advances in Quartz Crystals and Silicon Germanium BiCMOS Circuits Simplify High Speed Clock Generation for RF Data Converters

As the demand for higher frequencies and data rates and more accurate measurement capabilities increase, achieving ultra-low clock jitter for ADC and DAC converters becomes a critical specification. This paper illustrates how a high-quality crystal oscillator paired with a high-performance PLL/VCO enables small form factor, high-performance <30 fs clocks.
