| 主权项 | 1. An apparatus comprising: at least one differential amplifier configured to amplify a radio frequency signal; a mixer configured to mix the radio frequency signal from the at least one differential amplifier with a local oscillator signal; a low-pass filter coupled to the mixer, the low-pass filter includes a capacitor and at least one variable resistor configured to tune the low-pass filter; at least one single-ended amplifier configured to operate in a surface acoustic wave (SAW) mode; and a shared input node coupled to the at least one differential amplifier and the at least one single-ended amplifier. | ||
