Abstract
A transceiver includes a first circuit having a connector for connection to an antenna and receiving circuitry, and a second circuit having transmitting circuitry. The first and second circuits are coupled using a balun, where the balun is arranged so that its unbalanced side is in the first circuit and its balanced side is in the second circuit.
Claims25
A transceiver comprising;
- a first circuit comprising a connector for connection to an antenna and receiving circuitry;
- and
- a second circuit comprising transmitting circuitry;
- wherein the first and second circuits are coupled using a balun having first and second sides, the first side being an unbalanced side and the second side being a balanced side, the balun being arranged so that its first, unbalanced side is in the first circuit and its second, balanced side is in the second circuit.

A transceiver for receiving and transmitting data, comprising:
- a first circuit comprising a connector for connecting to an antenna and receiving circuitry;
- and
- a second circuit comprising transmitting circuitry;
- wherein the first and second circuits are coupled using a balun having first and second sides, the first side being an unbalanced side and the second side being a balanced side, the balun being arranged so that its first, unbalanced side is in the first circuit and its second, balanced side is in the second circuit;
- and
- wherein the unbalanced side of the balun is arranged in the first circuit in such a way that, when the transceiver is receiving a signal, the receiving circuitry receives a signal from the antenna through the unbalanced side of the balun.
