Abstract
Official abstract text for this publication.
Disclosed herein, among other things, are systems and methods for filtering to suppress harmonics for a hearing assistance device antenna. One aspect of the present subject matter includes a hearing assistance system for a wearer including a wireless radio frequency (RF) transceiver, an antenna and a filter connected between the RF transceiver and the antenna. According to various embodiments, the filter is configured to suppress harmonics for the antenna, and configured to maintain impedance and prevent inversion of impedance presented to the RF transceiver from the antenna.
First claim
Opening claim text (preview).
What is claimed is: 1 . A hearing assistance device, comprising: a wireless radio frequency (RF) transceiver; an antenna; and a balanced low pass filter connected between the RF transceiver and the antenna, the filter configured to suppress harmonics for the antenna and configured to prevent inversion of impedance presented to the RF transceiver from the antenna. 2 . The device of claim 1 , wherein the RF transceiver is configured to operate in a 900 MHz band. 3 . The device of claim 1 , wherein the RF transceiver is configured to operate using antenna tuning circuitry. 4 . The device of claim 1 , wherein the antenna is a resonant loop antenna. 5 . The device of claim 1 , wherein the filter is implemented using low temperature co-fired ceramic (LTCC) technology. 6 . The device of claim 1 , wherein the filter is implemented using thin film technology. 7 . The device of claim 1 , wherein the hearing assistance device includes a cochlear implant. 8 . The device of claim 1 , wherein the hearing assistance device includes a hearing aid. 9 . The device of claim 8 , wherein the hearing aid includes an in-the-ear (ITE) hearing aid. 10 . The device of claim 8 , wherein the hearing aid includes a behind-the-ear (BTE) hearing aid. 11 . The device of claim 8 , wherein the hearing aid includes an in-the-canal (ITC) hearing aid. 12 . The device of claim 8 , wherein the hearing aid includes a receiver-in-canal (RIC) hearing aid. 13 . The device of claim 8 , wherein the hearing aid includes a completely-in-the-canal (CIC) hearing aid. 14 . The device of claim 8 , wherein the hearing aid includes a receiver-in-the-ear (RITE) hearing aid. 15 . A method, comprising: providing a balanced low pass filter connected between an RF transceiver and an antenna of a hearing assistance device, the filter configured to suppress harmonics for the antenna and configured to prevent inversion of impedance presented to the RF transceiver from the antenna. 16 . The method of claim 15 , wherein providing a balanced low pass filter includes providing a balanced low pass filter using discrete LC technology. 17 . The method of claim 15 , wherein the RF transceiver is configured to operate in a 900 MHz band. 18 . The method of claim 15 , wherein the antenna is a resonant loop antenna. 19 . The method of claim 15 , wherein providing the filter includes using low temperature co-fired ceramic (LTCC) technology. 20 . The method of claim 15 , wherein providing the filter includes using thin film technology.
