Abstract
A wireless device is described. The wireless device includes an antenna. The wireless device also includes a hybrid transformer. The wireless device further includes a frequency matching termination port. The frequency matching termination port provides impedance matching with the antenna at multiple frequencies. The frequency matching termination port may include multiple resistors, inductors and capacitors that can be switched in/out.

A wireless device, comprising:
- an antenna;
- a hybrid transformer;
- and
- a frequency matching termination port, wherein the frequency matching termination port provides impedance matching with the antenna at multiple frequencies.
A method for impedance matching at multiple discrete matching frequencies, comprising:
- determining multiple discrete matching frequencies for frequency matching;
- and
- adjusting a frequency matching termination port to obtain impedance matching with an antenna for a hybrid transformer at the multiple discrete matching frequencies.
An apparatus for impedance matching at multiple discrete matching frequencies, comprising:
- means for determining multiple discrete matching frequencies for frequency matching;
- and
- means for adjusting a frequency matching termination port to obtain impedance matching with an antenna for a hybrid transformer at the multiple discrete matching frequencies.
A non-transitory computer-readable medium having instructions thereon, the instructions comprising:
- code for causing a wireless device to determine multiple discrete matching frequencies for frequency matching;
- and
- code for causing the wireless device to adjust a frequency matching termination port to obtain impedance matching with an antenna for a hybrid transformer at the multiple discrete matching frequencies.
