This is a tiny low noise amplifier that uses the PSA4-5043+. It has built-in input and output Bias Tees and can be powered with DC on the RF output cable (please refer to the block diagram in the product pictures). As well it provides DC voltage to an active antenna or another LNA upstream. Insert this LNA inline and as close to the antenna as possible to improve signal reception.
Any SDR such as RTL-SDR with at least +3.3V Bias Tee source can be used to power the device. The DC port can be used to test the DC voltage supply.
The LNA can be used in a number of different receiver applications such as Ham Radio, TV reception, etc. The product is ideally suited as a pre-amplifier and operates across a large DC supply range of +3.3V to 10V. The noise figure of this LNA is only 0.7 dB at 100 MHz.
• Wideband LNA operates from 10 MHz to 2 GHz
• 0.7 dB Noise Figure at 100 MHz
• LED power indicator
• SMA-F connectors
• Wide DC supply range +3.3V to +10V

Maximum RF Input Power
1. When using the DC header to power the device, the same DC voltage will appear on both the RF input as well as output. Some radio equipment cannot handle DC voltage at its input or output.
2. Connectors are SMA-F
