Patent ID: 7787833

Claim:
A broadband transmitter operable to transmit in-band signals in a broadband network, the broadband transmitter comprising: a modulator producing a modulated signal; a receiver for receiving the modulated signal and outputting an analog signal at a predetermined frequency; a low-linearity amplifier amplifying the analog signal at the predetermined frequency; and a micro-electro-mechanical systems (MEMS)-switched filter bank including at least one MEMS switch and at least one filter, wherein the MEMS-switched filter bank reduces in-band noise and harmonics from the amplified analog signal for transmission of the amplified analog signal at the predetermined frequency in the broadband network, wherein the low-linearity amplifier is operable to function using at least two input voltages including a higher voltage and a lower voltage, wherein the amplifier has a lower linearity when functioning at the lower voltage.
