Wireless Transceiver Using Shared Filters For Receive, Transmit And Calibration Modes

View page
US Patent:
8204451, Jun 19, 2012
Filed:
Jul 30, 2008
Appl. No.:
12/182232
Inventors:
Alireza Kheirkhahi - Irvine CA, US
Hirad Samavati - Santa Clara CA, US
Srenik Mehta - Union City CA, US
David Su - Santa Clara CA, US
Brian Kaczynski - Krakow, PL
Assignee:
QUALCOMM Atheros, Inc. - San Jose CA
International Classification:
H04B 1/40
US Classification:
455 84, 455 83, 455 82, 370280
Abstract:
A transceiver for use in a wireless device. The transceiver may include a receive portion for receiving an input RF signal. The receive portion may include at least one receive filter which may include a first filter. The transceiver may also include a transmit portion for transmitting an output RF signal. The transmit portion may include at least one transmit filter, which may include the first filter used in the receive portion. The transceiver may further include a plurality of switches, which may include a first switch coupled to an input of the first filter and a second switch coupled to an output of the first filter. The plurality of switches may be configurable to enable use of the first filter in the receive portion for receiving the input RF signal and use of the first filter in the transmit portion for transmitting the output RF signal.

US Patent:
20160233931, Aug 11, 2016
Filed:
Mar 21, 2016
Appl. No.:
15/076529
Inventors:
- San Diego CA, US
Didier Johannes Richard van Nee - Tull en 't Waal, NL
Simon Jan Brand - Pleasanton CA, US
Patrick Daniel Kelliher - Chelmsford MA, US
MeeLan Lee - Los Altos CA, US
Todd Daniel Antes - San Jose CA, US
Maarten Menzo Wentink - Naarden, NL
Alireza Kheirkhahi - San Jose CA, US
Ayse Yesilyurt - San Jose CA, US
International Classification:
H04B 7/04
H04B 17/12
Abstract:
In an aspect a transceiver is provided. The transceiver may include a plurality of local oscillator (LO) generators configured to generate a plurality of LO signals, respectively, for mixing with one or more communication signals. The transceiver also includes a first synthesizer configured to generate a first reference signal and a second synthesizer configured to generate a second reference signal. The transceiver also includes a distribution circuit. The distribution circuit is configured to switch an input to at least one of the LO generators between the first and second reference signals for tuning each of the at least one of the LO generators between two different LO frequencies and to input to the other ones of the LO generators the first reference signal for tuning each of the other ones of the LO generators to an LO frequency.
