INTRODUCTION
These are 1.5GHz-30W and 4GHz-1/4W surface mounted, small sized attenuators of 50 ohm characteristic impedance. The
TFA68D, 1.5GHz-30W, which can attach to a heat sink directly, is Pb and BeO free. The TFA68D is durable and can be used in
power consumption in isolators and circulators. The TFA53S and TFA54D 4GHz-1/4W exhibit high durability against pulse
/EMI accidents in small signal applications.
characteristics. Long life and temperature stability of the thin film technology gives better performance at a temperature
range from 55-155C.
Applications include:
compensation of transmission line and data communication systems, detecting signal control of ATE, LSI test systems and
circuit board functional test systems, industrial measurement electronics, medical scientific electronics and miscellaneous
communication systems.
