The LNA4ALL is a pre-amplifier and a low-pass...
The LNA4ALL is a pre-amplifier and a low-pass filter (LNA) with SMA female RF connectors and for RF frequencies covering all bands from 28MHZ to 2500 MHz.
It improves greatly reception performance, on VHF-UHF (up to 2.5GHz) bands, of a USB stick TNT / RTL-SDR or the HackRF One and Airspy.
Power is to build yourself via a 6V/9V by connecting simply 2 power cables or 5V with a modification on the board.
This material is no longer available, equivalent model: LNA PGA-103 50-2500Mhz F1OPA preamp.
Other model available: LNA 50-4000 Mhz preamplifier with SPF5189Z.
See also the LNA HF F1OPA version for 150KHz to 30MHz preamplifier HF bands.
Power supply: 6-9V DC or 5V (with modification-it-yourself)
Consumption: 18mA
Frequency range: 28MHz - 2500MHz
Receive gain: 11 to 23dB (cf. diagram)
NF: 0.75dB @ 1GHz
Amplifier: PGA-103+ (PGA103)
Impedance: 50 ohms
Antenna Connector: SMA Female
Dimension: 25x25 mm
The input and output of the antenna are tuned to 50 ohms, and there is no significant deterioration with cable TV 75 ohms also.
VERY IMPORTANT
This preamplifier LNA is highly efficient and need to be use with caution, never use near strong signal, nor transmit a signal radio nearby (FM radio station amateur radio, walkie-talkie, etc.) under penalty of "grill" your SDR receiver immediately!
How to protect the LNA from ESD?
The static discharge can damage the LNA if it is not protected and used properly.
1 - Never leave the LNA plugged permanently or placed permanently behind an antenna on the mast
2 - Disconnect the antenna and ensure proper grounding of the LNA and antenna, before reconnecting the antenna cable discharging static electricity
3 - It is also possible to add extra protection diode BAV99 welding (scratch first location) to the input of the antenna as shown in green on the following picture:
So if lightning the diode will be damaged but not the rest of the LNA card.
No LNA will be returned or exchanged due to misuse.
The warranty does not cover damage that may result from an assembly error, an incorrect antenna setting (ROS), a maximum input power not respected, a short circuit of the power supply or coaxial line and damage from electrostatic discharge.
