Wi-fi transceiver having dual-band virtual concurrent connection mode and method of operation thereof

摘要

A transceiver, a method of providing multiple-band virtual concurrent wireless communication and a wireless device incorporating the transceiver or the method. In one embodiment, the transceiver includes: (1) first transmit and receive intermediate frequency (IF) strips, (2) second transmit and receive IF strips, (3) first and second local oscillators (LOs) and (4) switches operable to multiplex clock signals from the first and second local oscillators to cause the transceiver to operate in a selectable one of: (4a) a unified, multiple-input, multiple-output (MIMO) mode in which the first and second transmit and receive IF strips are driven to transmit and receive in a first band and (4b) a concurrent multiple-band connection mode in which the first transmit and receive IF strips are driven in the first band and the second transmit and receive IF strips are concurrently driven in a second band.

主权项

1. A transceiver, comprising:
first transmit and receive intermediate frequency (IF) strips; second transmit and receive IF strips; first and second local oscillators (LOs); switches operable to multiplex clock signals from the first and second local oscillators to cause said transceiver to operate in a selectable one of:
a unified, multiple-input, multiple-output (MIMO) mode in which said first and second transmit and receive IF strips are driven to transmit and receive in a first band, anda concurrent multiple-band connection mode in which said first transmit and receive IF strips are driven in said first band and said second transmit and receive IF strips are concurrently driven in a second band; and digital baseband circuitry coupled to said first and second transmit and receive IF strips and including a media access controller (MAC) operable as a MIMO processor in said concurrent multiple-band connection mode.
