Custom solutions are available. AAC AT series high performance 0402, 0805, 1206, and 1612 size thin film fixed chip attenuators exhibit excellent high frequency characteristics. The surface mount package is ideal for low noise, inductance and parasitic capacitance applications. The thin film metallization also offers very stable characteristics over temperature and time. APPLICATION Gain adjustment and impedance matching in high frequency circuits. Because control circuits need signals with identical levels, and a receiver receives signals with different signal levels, signal levels could be adjusted by combining a SMT attenuator and amplifier. At the same time, termination can be obtained using these low reflection attenuators.
