LNA 30 wide band preamp. 5 kHz - 30 MHz

Product.Nr.: 1014

product description

The LNA 30 is a broadband amplifier for applications in the frequency ranges VLF, LF, MW and HF. Signals above 30 MHz are strongly suppressed by a low pass at the input of the amplifier. The MMIC used enables a low noise figure with high large signal strength. This amplifier is supplied with 12 to 24 V voltage via the UHF socket. Alternatively, the device can be powered by a 24 V battery. The highest large signal strength is achieved with a 24 V voltage supply and the smallest noise figure at 12 V. Only linear power supplies are recommended for the voltage supply of the LNA 30. Switching power supplies generate a large interference level in the low frequency ranges and are not suitable for this application.
