The LimeRFE is a multiband preamp and PA unit with switched filters specifically designed to be used with the LimeSDR. It can provide a useful output of 1W or so of DATV on all bands from 71 MHz to 2.4 GHz and slightly reduced output on 3.4 GHz.

		+	The LimeRFE can be controlled from a Portsdown 4 over USB.
		+
		+	===Configuration===
		+
		+	Configuration data for the LimeRFE is stored for each Portsdown Band. The parameters that are configured are:
		+
		+	* LimeRFE Enabled/Disabled
		+	* LimeRFE transmit Output Port (TX/RX (1), TX (2) or HF (3))
		+	* LimeRFE receive attenuator setting (0 - 14 dB in 2 dB steps)
		+
		+	The Enable/disable and attenuator setting can be set for the current band from the Lime Configuration Menu. To select the TX output port, use the "Set Band Details" Menu.
