LUOWAVE SDR RF Rx Tx Daughterboards WBX-LW 120MHZ Compatible with USRP

Main Features：
1. Frequency coverage： 50 MHz - 2.2 GHz
2. Maximum bandwidth includes： 40 MHz 、 120 MHz
3. The WBX RF daughter board contains a full-duplex wideband transceiver that supports up to 120 MHz of instantaneous bandwidth
4. Serving a wide range of applications: public safety, communications, amateur radio and ISM
5. The local oscillator's receive and transmit chains operate independently, allowing for frequency duplex operation
6. The reference for the local oscillator is the master clock from the USRP, allowing multiple coherent operations
7. Suitable for USRP-LW X300 / x310 devices
