2- and 3-dB peak gain radio

[sverchok]

...the BlackChip miniature antenna is presented as the industry’s first at that size to combine dual-band narrow and wide frequency-range support—2.4 to 2.5 GHz and 4.9 to 6.0 GHz—with RF performance of 2- and 3-dB peak gain across those respective frequencies.

The actual radiating element of the new Laird Technologies’ BlackChip™ is an
incredibly small 96 mm³. Its performance is > 2 dB peak gain across 2.4 –
2.5 GHz and > 3 dB peak gain across 4.9 – 6.0 GHz.

Его характеристики: пиковое значение усиления больше 2 децибелл в диапазоне 2.4-2.5 ГГц и больше 3 децибелл в диапазоне 4.9-6.0 ГГц
