Abstract
A radio that includes a transceiver to transmit and receive RF signals. The transceiver including a transmitter, a transformer, and a receiver, the transformer is coupled to and shared between the transmitter and the receiver. A resonator is formed by the combination of the transformer and capacitive elements of the transmitter and receiver.
Claims20
A radio, comprising:
- a transceiver to transmit and receive RF signals and comprising a transmitter, a transformer, and a receiver;
- wherein the transformer is coupled to and shared between the transmitter and the receiver and a resonator is formed by the combination of the transformer and capacitive elements of the transmitter and receiver.
A low-power transceiver, comprising:
- a transmitter to amplify a first RF signal for transmission and comprising a first amplifier stage, a transformer, and a second amplifier stage, wherein the first amplifier stage is coupled to the second amplifier stage through the transformer;
- and
- a receiver to receive a second RF signal and comprising an amplifier, the transformer, and a mixer, wherein the amplifier is coupled to the mixer through the transformer.
The transceiver of claim 10, the transmitter further comprising a phase locked loop (PLL) coupled to a voltage controlled oscillator (VCO), the VCO is coupled to the first amplifier stage, and a third amplifier stage coupled to the second amplifier stage.
A wireless communication device, comprising:
- a transmitter comprising a first amplifier stage to amplify an RF signal received from a voltage controlled oscillator (VCO);
- a second amplifier stage to generate gain for the RF signal;
- a transformer coupled between the first amplifier stage and the second amplifier stage;
- a receiver comprising an amplifier to amplify a received RF signal and a mixer;
- the transformer coupled between the amplifier and the mixer.
