Estimating the term…
A dual band radio is constructed using a primary and secondary transceiver. The primary transceiver is a complete radio that is operational in a stand alone configuration. The secondary transceiver is a not a complete radio and is configured to re-use components such as fine gain control and fine frequency stepping of the primary transceiver to produce operational frequencies of the secondary transceiver. The primary transceiver acts like an intermediate frequency device for the secondary transceiver. Switches are utilized to divert signals to/from the primary transceiver from/to the secondary transceiver. The switches are also configured to act as gain control devices. Antennas are selected using either wideband or narrowband antenna switches that are configured as a diode bridge having high impedance at operational frequencies on control lines that bias the diodes.
A wireless LAN device having a dual band RF capability.
The wireless LAN device according 70, further comprising a detection selection switch configured select the primary signal strength detector for detecting transmit signal strength when the primary transceiver is transmitting and select the secondary signal strength detector for detecting transmit signal power when the secondary transceiver is transmitting.
A dual band capable wireless device, comprising:
A method of performing wireless LAN (WLAN) communications with a dual band WLAN device, comprising the steps of:
