Wideband Low Noise Amplifier with integrated FM band filter
The FM stop band filter attenuates the rest of the FM broadcast staions between 87 and 107 MHz. It\'s an ideal choice, if you have strong FM transmitters around you. This new wideband LNA works from 2 to 1000 MHz, and suppress the annoying FM radio stations. This way you can get a better signal to noise ratio, and cleaner reception.
Features:- Operating frequency: 1 MHz - 2.6 GHz- Stop band: 87.5 - 107 MHz (FM broadcast band)- Stop band attenuation: -30 dB @ 98 MHz- RF Gain: - 50 MHz: +16 dB - 145 MHz: +16 dB - 450 MHz: +15 dB - 1090 MHz: +12 dB - 2.5 GHz: + 4 dB- Low Noise Figure: 1.6 dB @ 120 MHz- Low current consumption: <60 mA- Supply voltage: 5V via microUSB / 7.5-15 VDC via PCB terminals / Phantom power over coaxial cable (7.5-15V)- RF connectors: gold plated SMA female connectors, with 50 Ohm input/output impedance- On-board power indicator LED
Thanks to the proper design, this LNA is a perfect choice to use with RTL SDR Radios (LF, HF, VHF, UHF), or with any airband or ADS-B receiver. This compact sized LNA filters out the strong FM stations neor to you, and amplifies the far and weak signals out of FM band. It\'s an ideal choice, if you would like to use a wideband LNA, but you have strong FM interferences around you.
Circuit can be powered via a standard microUSB connector (using an USB cable from PC, or using any cellphone charger with microUSB plug), or it is also possible to power the amplifier via the onboard terminal points from an external power supply. A third way to power the LNA is using phantom power over the coaxial cable (7.5-15V).The integrated voltage regulator ensures that any power source with output voltage from 7 V to 15 VDC will work. The power input is protected against reverse polarity.Mounting the board is very easy, thanks to the standard 3 mm fixing holes on the board.
Please note, that PCB color is subject to change (red or blue). Orders from 2nd May will be shipped on red circuit board.
Package includes:- 1 piece of LNA with integrated FM notch filter (100% tested and assembled)- 1 piece of printed manual/connection diagram (in English)
