Providing an output power of 40 ~ 500KHZ frequency signal amplifier
Date:2021/10/18 21:55:56 Hits:
This power amplifier is mainly to provide sufficient output power to 40 to 500 kHz frequency signals to meet the requirements of high frequency levels.
The technical indicators are as follows: 1. Frequency range: 40 ~ 500kHz2, frequency characteristics: deviation does not exceed the positive loss of 0.5 dB (centered on 250 kHz) 3, gain and adjustment range: 45 positive and negative 5DB4, rated output level: 0dBm5, rated output Level: less than or equal to 45dBm6, maximum lossless power: 25W (peak envelope power) 7, overload level: less than or equal to 50 dBm8, input impedance: 75 o'clock, unbalanced, reflection coefficient P is greater than or equal to 15% 9 , Output impedance: 75 euros, unbalanced, reflection coefficient P is greater than or equal to 15%
