This low noise amplifier module is used as a high frequency or intermediate frequency preamplifier for UHF and VHF band radio receivers, as well as an amplification circuit for highly sensitive electronic detection equipment Low noise amplification: This amplifier is designed to minimize noise and can provide clear and powerful signal enhancement without adding unnecessary interference, which is very suitable for critical communications and spectrum analysis Using low noise LNA tube core, the low end frequency can be as low as 10KHz Using CNC shell packaging, it has excellent electromagnetic shielding performance 40dB high gain characteristics, high flatness, widely used in the front end of broadband receiver systems, and can also be added to the input of the spectrum analyzer to improve sensitivity Working voltage: +5V single power supply Working current: 75mA (low power consumption) Working frequency: 1MHz-1.5GHz Gain: 40dB typical value (see test curve) P1dB output power: +4dBm; Noise figure: 2.4dB Input and output interface: SMA (external screw and internal needle) Colour:As Shown Material:CNC Due to different batches, there may be differences in product appearance and printed text, which not affect use Package Contents: 1 * Low Noise LNA Amplifier Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
