Abstract
Official abstract text for this publication.
The exemplary embodiments include a radio frequency antenna switch configured to reject harmonic frequencies. In addition, the harmonic-rejected radio frequencies of the radio frequency antenna switch may be tuned by use of a capacitor array. The capacitor array may be configured with fuse elements or by control logic.
First claim
Opening claim text (preview).
What is claimed is: 1. A multiport radio frequency switch comprising: a first plurality of switches; a second plurality of switches; an antenna port configured to couple to an antenna; a first inductor having a first end and a second end, the first end of the first inductor electrically coupled to the antenna port, and the second end of the first inductor electrically coupled to the first plurality of switches; a second inductor having a first end and a second end, the first end of the second inductor electrically coupled to the antenna port, and the second end of the second inductor electrically coupled to the second plurality of switches; a capacitor array having a first end and a second end, the first end of the capacitor array electrically coupled to the second end of the first inductor, and the second end of the capacitor array coupled to the second end of the second inductor, wherein the first inductor and the second inductor are configured in series to form an inductor series, and wherein the capacitor array is configured in parallel with the inductor series. 2. The multiport radio frequency switch of claim 1 wherein the capacitor array is a programmable capacitor array. 3. The multiport radio frequency switch of claim 2 wherein the programmable capacitor array is coupled to control logic, wherein the control logic is configured to program the programmable capacitor array.
