Patent number: 7991363Abstract: A tunable matching circuit is adjusted primarily based on transmitter oriented metrics and is then applied to attain a desired tuning for transmitter and receiver operation. In a TDM system, this is accomplished by identifying an optimal tuning for the transmitter and then applying an empirically derived adjustment to the tuning circuit in receiver mode. In an FDM system, this is accomplished by identifying a target operation that is a compromise between transmitter performance and receiver performance, and then adjusting the tuning circuit as a function of transmitter metrics and the current tuning values to achieve the desired compromised performance.Type: GrantFiled: November 14, 2007Date of Patent: August 2, 2011Assignee: Paratek Microwave, Inc.Inventor: Matthew R.
