Excellent RF-Temperature Characteristic of TCA series at 1GHz, 3GHz and 6GHz

Yantel`s temperature compensation attenuator has a wide attenuation variable range in the temperature from -55 ℃ to +150℃ at 1GHz, 3GHz and 6GHz. Meanwhile, the attenuation tolerance and VSWR is very low at 1GHz, 3GHz and 6GHz.This acteristic makes it more suitable in wide frequency range application, like 5.3~5.8GHz WLAN and UWB. When customers look for higher frequency for good telecommunication, Yantel can offer the competitive cost solution of excellent RF performance (at 1GHz, 3GHz and 6GHz) and competitive cost.
