摘要： A GPS signal receiving method in a mobile terminal having a first reception path and a second reception path is provided. Upon request for GPS signal reception while receiving a CDMA signal in the first reception path, the received strength of a GPS signal is measured. If the GPS signal strength is equal to or greater than a predetermined threshold, the GPS signal is received in the first reception path. If the GPS signal strength is less than the predetermined threshold, the GPS signal is received in the second reception path.

摘要： A radio transmission/reception system using the same frequency includes a power control circuit which can prevent a sensitivity of the receiver from being lowered due to the carrier radiated from the transmitter, and finely control the power. The power control circuit includes first and second variable attenuators being respectively installed at an intermediate frequency stage and a local oscillator frequency stage, so as to finely control the power level of a next radio frequency stage. A CPU (central processing unit) controls amounts of attenuation of the first and second variable attenuators. Each of the first and second attenuators includes a first pin diode connected so as to be turned on in response to a signal level from the intermediate frequency stage and so as to generate a first current flowing toward an output of the attenuator, and a second pin diode connected so as to be turned on in response to a signal level from the central processing unit and so as to generate a second current flowing in an opposite direction of the first current.

摘要： A method and apparatus are provided for removing cross modulation (CM) noise in a wireless transceiver. A determination is made as to whether a transmission signal to be supplied to a transmitter of the wireless transceiver is present. If the transmission signal is present, a level of the transmission signal is determined. When a value of the transmission signal level is equal to or greater than a predetermined value, a first number of filtering operations are performed on a received signal to be input into a receiver of the wireless transceiver. However, when no transmission signal is present or the value of the transmission signal level is less than the predetermined value, a second number of filtering operations are performed on the received signal to be input into the receiver of the wireless transceiver. The first number of filtering operations being greater than the second number of filtering operations.

摘要： Disclosed is a multi-mode/multi-band wireless transceiver. The multi-mode/multi-band wireless transceiver includes a tunable duplexer including transmission and reception channel filters of which transmission and reception channel filtering frequencies respectively are controlled by an external element; and a control portion for controlling the transmission and reception channel filtering frequencies to correspond to transmission and reception channels of a current service band. Thus, a use of a RF SAW filter is unnecessary, while it is possible to support the multi-mode/multi-band using a tunable duplexer. Therefore, the number of parts and volume of the transceiver can be reduced, and it is possible to weaken a specification of an RF system.
