Abstract
Telsiz cihaz tarafindan alinan bir sinyalin kuvvetinin ya da telsiz cihazin bir vericisinin bir nakil gücünün en azindan birine dayanarak, bir düsük noyzlu yükselticinin üçüncü düzey kesisme noktasinin ayarlanmasiyla alicinin güç tüketimini düsürecek sekilde bir telsiz cihazin bir alicisinin çalismasini kontrol eden yöntemler, sistemler ve bilgisayar programi ürünleri temin edilmistir. Bundan baska, düsük noyzlu yükselticinin kazanci ayni zamanda alinan sinyal kuvveti ya da verici gücüne dayanilarak da ayarlanabilmektedir. Ayni zamanda, alicinin bir mikseri ile birlesik bir yükselticinin kazanci alinan sinyal kuvveti ya da verici gücüne dayanilarak ayarlanabilmektedir. Tercihen, güç tüketiminin telsiz cihazin operasyon kosullarina uydurulmasi için birden çok güç modu temin edilmistir.
