Chip attenuator, with a maximum power of 250 watts and a maximum frequency of 18 GHz. The standard attenuator uniformly reduces RF power at all temperatures, while the temperature-variable chip design reduces its attenuation at high temperatures to provide the optimal response required for signal leveling applications. The sheet-type attenuator is used in amplifier circuits, receivers, up/down converters, phase-matching arrays, and switch applications. According to the required specifications, the chip can be manufactured on BeO, aluminum nitride, or aluminum oxide ceramics with thin or thick resistors.
