Lead Free RF SOLUTIONS – WILLOW TECHNOLOGIES LTD SURFACE MOUNT RF POWER ATTENUATORS RFA53, RFA54, RFA55, RFA68, RFA85, RFA37 Features and Applications 1.5GHz-30W and 4GHz-1/4W surface mount small size attenuators of 50ohm characteristic impedance. RFA68D, 1.5GHz-30W (attach to heart sink directly) small size power attenuator, Pb free / BeO free configuration, RFA68D has durable power consumption in power isolators and circulators. RFA53S and RFA54D 4GHz-1/4W power and high durability against pulse / EMI accidents in small signal applications. Face down configuration on strip line show better return loss characteristics. Long life and temperature stability of thin film technology realize better performance at a temperature range from –55C to +155C. Applications include gain control circuits, isolation circuits of power boost amplifiers at GHz, loss compensation of transmission line of data communication systems, detecting signal control of ATE-LSI test system-circuit board functional test systems, industrial measurement electronics, medical scientific electronics and miscellaneous communication systems.
