Airband low noise amplifier with integrated band pass filterMain features: - Typical airband gain: +14 dB (117-136MHz)- High attenuation for FM broadcast and for PMR band - Wide power supply range: 7-15 VDC, phantom power also can be used through the coaxial cable - Low power consumption: < 60mA- SMA female connectors- Input/Output impedance: 50 Ohm - On-board power indicator LED - Small dimensions: 16 X 28 mm (PCB size)
Circuit was designed to use as a high gain, low noise amplifier for the airband. As an extra feature, an onboard band pass filter is integrated onto the circuit board, tuned between 117 and 137 MHz. This way signals below 110 MHz and above 145 MHz are strongly attenuated, so reception in the airband will be more clear and non-disturbed. Commercial FM broadcast transmitters and radio amateur's PMR radios are filtered very well. Fm stations are suppressed by -10-20dB, PMR radios by more than -64dB!You can power the circuit with any standard power supply, with output voltage between 7 and 15 VDC. A more simple way to power the LNA is using the coaxial cable itself (phantom power). Applying phantom power supply, you can place the LNA right next to the antenna, and have maximum SNR.Please note, that this LNA is not suitable for transmitters, you can use it only with receivers, tuners, or with transceivers in rx mode. If you connect the circuit to a transmitter, the RF power will demage the LNA.
Package includes:- 1 piece of assembled and tested LNA for the airband- 1 piece of printed user manual in English
