AIS + WEATHER BAND PRE-FILTERED LOW NOISE AMPLIFIER WITH BIAS TEE 160-164 MHz

PRODUCT DESCRIPTION

Small and cost-effective Pre-Filtered Low Noise Amplifier 160 - 164 MHz with excellent rejection of FM band. Within the AIS and Weather Radio Bands, the Gain is 20 dB while the Noise Figure is less than 1 dB. The RF Input has an ESD diode for static protection.

The device can be powered using either the Micro USB port, with a DC supply using the two-pin header or over the output RF cable using the built-in Bias Tee. The Bias-Tee voltage should be at least +4.3V and must not exceed an absolute maximum of +12V.

Weather radio broadcasts in the United States (NOAA NWR) and Canada (Weatheradio Canada) occur on seven dedicated frequencies: 162.400, 162.425, 162.450, 162.475, 162.500, 162.525, & 162.550 MHz.

AIS or Automatic Identification System operates at 161.975 MHz & 162.025 MHz.

** 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.

**

It is recommended that the USB Bias Tee be used to power this module. This is an option on the product page.
