<p>A low-noise block converter (201) comprises a low-noise amplifier (202), a local oscillator (203), a mixer (204), an IF-amplifier (205) and a regulator (206). The low-noise amplifier (202) amplifies a high-band received signal. The local oscillator (203) generates a local-frequency signal. The mixer (204) transforms the high-band received signal into an intermediate-frequency signal by mixing the high-band received signal with the generated local-frequency signal. The IF-amplifier (205) amplifies the intermediate-frequency signal. The regulator (206) is connected to the IF-amplifier (205) to provide a steady current (or voltage) to the local oscillator (203), the mixer (204) and the low-noise amplifier (202).</p> |
