Abstract: A wireless telephone is disclosed having two antennas and associated filters tuned to first and second frequency bands, respectively. A selection device selects one of the antennas under the control of a frequency management device for connection to a transforming circuit. The transforming circuit includes a symmetrizing circuit which receives an asymmetric signal from one of the two antenna. The symmetrizing circuit is tuneable in response to a tuning voltage from a frequency management device. The symmetrizing circuit provides a symmetric output to an amplifier for amplification and subsequent conversion to an intermediate frequency using a mixer and a local oscillator.
