Transponder (satellite communications)
open-in-new
<h2 id="transponder-equivalent">Transponder equivalent</h2> <p>A transponder equivalent (TPE) is a normalized way to refer to transponder bandwidth. It simply means how many transponders would be used if the same total bandwidths used only 36 MHz transponders.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a><a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a><a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> So, for example, the <a href="/facts/ARSAT-1/t8uSy7D5">ARSAT-1</a> has 24 IEEE <a href="/facts/Ku_band/czTuuqpT">Ku band</a> transponders: 12 with a bandwidth of 36 MHz, 8 with 54 MHz, and 4 with 72 MHz, which totals to 1152 MHz, or 32 TPE (i.e., 1152 MHz divided by 36 MHz).<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a><a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Roddi, Dennis (2024).
