Patent number: 9544011Abstract: A system for use in a mobile device comprises: a switch unit configured to switch a common connection of a transmitter and a first receiver from a first antenna to a second antenna and a connection of a second receiver from the second antenna to the first antenna; and a processing system configured to receive at least two reception signals from the first and second receivers; in response to receiving the two reception signals, evaluate a communication link via the first and second antennae; based on the evaluation of the communication link, determine that the transmitter needs to transmit via the second antenna; obtain reception parameters used by said first and second receivers; cause the switch unit to switch the common connection of the transmitter and a first receiver so that the transmitter transmits via the second antenna; and exchange reception parameters between the at least two receivers.Type: GrantFiled: February 9, 2016Date of Patent: January 10, 2017Assignee: BROADCOM CORPORATIONInventors: Seppo Olavi Rousu, Samuel Vehkalahti

Patent number: 9288031Abstract: A switch arrangement comprises a first and second single pole switch. The pole of the first switch can selectively connect to a first and second path. The pole of the second switch can selectively connect to the first and second path. The first switch is configurable for a first mode of operation to connect a RF signal received at the pole to the first path to form a RF transmitter chain. The second switch is configurable for the first mode to connect the pole to the first path to form a RF receiver chain for receiving a RF signal. The first switch is configurable for a second mode to connect a RF signal received at the pole to the second path to form a second RF transmitter chain.Type: GrantFiled: April 2, 2014Date of Patent: March 15, 2016Assignee: BROADCOM CORPORATIONInventors: Seppo Olavi Rousu, Samuel Vehkalahti, Jarkko Petteri Mykkanen
