WIRE/WIRELESS TELECOMMUNICATION EQUIPMENTS WITH INTERFERENCE SUPPRESSION SYSTEM FILTER MODULE

摘要

PURPOSE: An application of an ISS(Interface Suppress System) filter module for a wired and wireless communication apparatus is provided to promote power efficiency by reducing power loss due to heat. CONSTITUTION: A pre-distorter(20) linearizes signals by offsetting IMD(Inter-modulation Distortion) for the signal of an output terminal and input signals. An ISSFU-PBAR-SDR(Interference Suppression System Filter Unit-Polymer base Bulk Acoustic Resonator-Software Define Radio)(30) increases an ACLR(Adjacent Channel Power Leakage Ratio) by controlling the output signal of a first operating amplifier(10). The ISSFU-PBAR-SDR converts the output signal into frequency signals including the fixed gain and power. An adder(40) combines the amplified signal of a second operating amplifier(11) and the signal which passes through the ISSFU-PBAR-SDR. A power amplifier(50) amplifies the total signals.
