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

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.
