This is a 4400 - 4950MHz low-noise amplifier (LNA) module specifically for the field of satellite communications (satecom).
As an RF low noise amplifier (RF Low Noise Amplifier), it performs well in signal processing. In the passband range of 4400 - 4950MHz, it can achieve a passband gain of 22.0 - 25.0 dB (including ripple), and the peak-to-peak ripple is only 1 dB (within 10 MHz bandwidth), which effectively guarantees the stable amplification of the signal. Its noise figure is as low as 2.2 dB, which greatly reduces the noise introduced during the signal amplification process and ensures the purity of the signal, which is crucial for the reception of weak signals in satellite communications.
The input third-order intercept point (IIP3) of this LNA module is -7.5 dBm, with good linearity, and can effectively deal with strong interference signals. At the same time, it has excellent suppression ability from antenna to receiving end in different frequency bands, enhancing the anti-interference ability of signal reception. In terms of RF power processing, the receiving output can reach 15 dBm, and the antenna input is 10 dBm, which meets the power requirements of various satellite communication scenarios.
In terms of power supply and physical characteristics, the DC input voltage requirement is 11-13 VDC, the current is less than 60 mA, the mechanical size is 5.4*3.4*1.8cm, the weight is only 0.062kg, and it can work stably in an ambient temperature of -20℃ to +70℃. Whether in ground stations or satellite equipment, this LNA module can provide reliable support for the stable operation of satellite communications with its excellent performance.
