SLL Management Algorithm Flow

Side Lobe Level, SLL, are undesired radiation characteristic of any antenna or antenna arrays.

Many companies spent significant amount of time and resources during the prototype development phase to mitigate SLL and qualify/certify the radiation pattern by FCC.  The issue which remains is two folds even after they succeed to meet FCC and regulatory requirements.

First, the SLL mitigation technique used are not optimum design performances and typically sacrifice antenna gain and power efficiency of Power Amplifier to meet regulations.  This in turn translates to lower C/N and/or Eb/N0, therefore lower throughput.  In other words, the transmitter suffers power efficiency as well as optimum throughput, two critical metrics for any transmitter in exchange for mitigating SLL, which should have been part of original design to begin with, hence lack of optimum design.

Spending resources to design efficient power amplifier, yet backing off from efficiency sweet spot of Power Amplifier due to undesired and uncontrolled SLL defeats the purpose of the overall system metrics; that power efficiency and throughput, both of which impact bottom lines of the network operator.

Second, the additional time which takes for trial and error is reducing the chances of being in the market during the window of opportunity.

ORTENGA SLL Management Algorithm is proactive design and embedded during the development phase to expedite TTM while producing optimum design trade-off Gain vs. SLL, hence power efficiency and throughput, below algorithm flow.
