낮은 노이즈 와이드밴드 앰프 LNA 신호 리시버 -30db
(Low Noise Wideband Amplifier Signal Receiver -30db)
개요
- 본 제품은 낮은 노이즈를 가진 LNA 앰프 모듈입니다.
- 동작 주파수는 0.1-2000Mhz로 다양한 RF 리시버 front-end에 적용하여 통신 거리를 늘리는데 사용할 수 있습니다.
- 단파, FM 라디오 등의 Low Noise RF signal Amplification이 필요한 곳에 사용이 가능합니다.
특징
- Size: 25*52mm
Diameter of end: 5mm
Operating frequency: 0.1-2000MHz
Amplifier gain:
F=0.1MHz, gain=32dB
F=500Mhz, gain=31dB
F=1000MHz, gain=29dB
F=1500Mhz, gain=25dB
F=2000MHz, gain=20dB
Maximum power output: +10dBm (10mW) @1dB Compression point
Power supply voltage: 6-12 VDC
System impedance: 50Ω - Tips:
1.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.
2.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.
3.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
4.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.
5.When the voltage is 12 v, reach maximum gain, the low frequency end gain of 32.5 dB.
