This is a 1420 MHz pre-filtered low noise amplifier for Hydrogen Line measurements that provides excellent gain and noise figure. This variant of the product has a Bias Tee installed on the output so it can also be powered with a DC supply over the RF cable provided by the receiver. It can also be powered using a micro-USB cable. A two pin header pad is also provided so that a DC supply ranging from +5V to +12V can be used instead to power the LNA.
Please note the following precaution since the Bias Tee is installed. When powering the device using either the DC header or the USB connector, +5 VDC will appear on the RF output. If your receiver does not have a DC blocking capacitor on its input or some other form of DC voltage protection, this voltage WILL damage your receiver.

BIAS TEE Note
Please note that this module has a Bias Tee on the output. If it is powered using the DC header or USB connector, there will be a DC voltage present on the Output of at least +5 V. If your receiver cannot tolerate DC, you will need to use a blocking capacitor between the output of this module and the input of your receiver.
When powering this module using a Software-defined radio or receiver that has a Bias Tee, you can check the voltage on the Header using an inexpensive multimeter. Please ensure that it is at least +5V DC and it should not exceed +12 VDC. Exceeding this max will damage the device. Supplying less than +5V DC will result in unreliable or no amplification.
