Features and Applications
5GHz-1W surface mount small size attenuators of 50ohm
characteristic impedance.
CQA44DD 5GHz-1W power and high durability against pulse /
EMI accidents in small signal applications.
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.
