Description: Item Name: RF Wideband Amplifier Module Operating frequency: 0.1-2000MHz Maximum Power Output: +10dBm (10mW) @1dB Compression point Power Supply Voltage: 6-12V DC Noise Figure: 1.9dB System Impedance: 50Ω Diameter of End: 5mm Size: 25*52mm
Note: – When working frequency is less than 500 MHZ, it get well gain flatness, can make it less than 1dB after careful adjustment. The lower frequency the higher gain consistency. – Amplifier working frequency of the lower limit is subject to input and output capacitor, the default value is 0.1 uF, working to 0.1 MHz. Increase the input and output capacitance appropriately,can extend the cut-off frequency, such as 10uF capacitance can work to 5KHz. – When the power supply voltage changes in 5-8 v, it can be used as a variable gain amplifier, gain increases with the increase of the power supply voltage, which suitable for radio frequency receive front-end circuit, using DA control power supply voltage, to control the gain of the amplifier, automatic gain control. – When the power supply voltage in the 8-10 v, the low frequency end gain up to 30 db, at this time the amplifier has a low noise coefficient and good stability.
