TQP4M9071 模拟衰减器
The TriQuint TQP4M9071 is a monolithic variable attenuator which operates from 2 to 20 GHz. This analog attenuator can operate from a single +2.5 volt power supply if used with an external variable voltage divider circuit. Typical RF performance at 10 GHz includes an insertion loss of 2 dB, maximum attenuation of 15 dB at 10 GHz and input/output return loss of greater than 10 dB. The device is an absorptive attenuator designed using MESFET technology employing a "PI" configuration which reduces bias currents and simplifies bias networks. The broadband capabilities of this device are versatile in many applications such as telecommunications, military and space. This device has a space heritage. DC blocking capacitors are provided on-chip. Bond pad and backside metallization is gold plated for compatibility with eutectic attachment methods as well as thermocompression and thermosonic wire bonding processes. The TQP4M9071 is supplied in chip form and is readily assembled using automated equipment. Ground is provided to the circuitry through vias the backside metallization.
