International Classification:

H04B001/38

US Classification:

455/553100, 455/552100

Abstract:

A radio frequency (RF) front-end () employed in a dual-mode transceiver module connects a first and a second dual-band antennas (), and includes a first and a second signal receiving paths for receiving RF signals in two different frequency bands, a first and second signal transmitting paths for transmitting RF signals in the two different frequency bands, and a switch unit connecting the first and second dual-band antennas with the first and second signal transmitting and receiving paths. The switch unit includes a double pole double throw (DPDT) switch () and two single pole double throw (DPDT) switches (). The switch unit performs an antenna selection function for both the first and second transmitting paths and the first and second receiving paths.

Appl. No.:

8/832447

Inventors:

Marcus Escobosa - Placentia CA
Youping Yun - Monterey Park CA
Fusheng Frank Chen - Santa Ana CA

Assignee:

Universal Electronics Inc. - Cypress CA

International Classification:

G09G 508

US Classification:

345158

Abstract:

A wireless control and pointer system for controlling electronic equipment. The system generally includes a hand held remote control comprising a first infrared signal emitter for use in transmitting a first infrared signal comprising a plurality of signal components each of which is transmitted at a first frequency but out of phase with respect to the other of the plurality of signal components and a receiver comprising an infrared signal sensor adapted to receive the infrared signal, a circuit connected to the infrared signal sensor for generating an orientation signal indicative of the orientation of the remote control as a function of the amplitude of each of the plurality of signal components of the infrared signal, and an interface circuit for transmitting a command signal indicative of the orientation signal to the electronic equipment.
