The radio circuit generates a transmission magnetic field when the radio circuit is transmitting transmit signals.

The radio circuit and the radio tag are co-located on a circuit board or are commonly powered.

These loud impulses overdrive the radio circuitry.

A software defined radio includes a radio circuit and an executable radio software system operable with the radio circuit and conforming to the software communications architecture (SCA) specification.

The wireless IC tag is provided with a wireless IC chip (10) and two coil-shaped antennas (20A), (20B).

A radio circuit comprising such a mixer arrangement and a communication apparatus comprising such a radio circuit are also disclosed.

An electronic device comprises the antenna device and a radio circuit connected to the transistor circuit.

The local oscillator circuit may cooperate with a radio circuit for providing wireless reception or transmission.
