For the LIMESDR-Mini [https://discourse.myriadrf.org/t/rf-connection-10-u-fl-connectors-6-rx-4-tx/305/9](https://discourse.myriadrf.org/t/rf-connection-10-u-fl-connectors-6-rx-4-tx/305/9)

> [@RF connection: 10 U.FL connectors (6 RX, 4 TX)?](https://discourse.myriadrf.org/t/rf-connection-10-u-fl-connectors-6-rx-4-tx/305/9):

> LMS7002M has 3x Rceiver RF inputs and 2x Tx output per channel. By design receiver inputs are tuned as follows:
> 
> LNAL - from 0.1 MHz to 2000 MHz. Gives a noise figure \<2dB.  
> LNAH - from 1500 MHz to 3800 MHz. Gives a noise figure \<3dB.  
> LNAW - from 0.1 MHz to 3800 MHz. Gives a noise figure 5-7dB. Usually used for sniffing.
> 
> Transmitter output bu design are similar and supported frequency range is form 0.1-3800 MHz.
> 
> However, every RF input/output is combined with RF matching network which might be band specific. On the LimeSDR the RF inputs/outputs are tuned for:
> 
> LNAL - is tuned for 800 - 900 MHz (3GPP Band V).  
> LNAH - is tuned for 1900 MHz (3GPP Band I).  
> LNAW - has broadband matching up to 2000 MHz.  
> TXout1 - is tuned for 2600 MHz (3GPP Band VII) .  
> TXout2 - has broadband matching up to 2000 MHz.
> 
> The matching network includes broadband Balun + network for fine tune for specific band, hence can be easily modified.

does anyone have this information for the limesdr-mini?

Sorry about that, putting auto-restart in place.
