Abstract:
1. Radio frequency (RF) signal conditioning circuitry comprising: RF detection circuitry adapted to receive and detect an RF sample signal to provide an RF detection signal; and RF attenuation circuitry comprising an attenuation circuitry input, an attenuation circuitry output, a first series attenuation resistive element and a second series attenuation resistive element coupled in series between the attenuation circuitry input and the attenuation circuitry output, a first shunt attenuation resistive element coupled between a ground and a junction of the first series attenuation resistive element and the second series attenuation resistive element, and a second shunt attenuation resistive element coupled between the attenuation circuitry output and the ground, wherein the RF attenuation circuitry is adapted to: wherein the RF detection signal and the attenuated RF signal are provided concurrently, and the RF signal conditioning circuitry includes no switching devices.
