TQ9161

The TQ9161 is a kind of voltage-controlled absorptive attenuator designed for gain compensation/control and leveling loop applications. Internal circuitry maintains good input/output return loss as attenuation is varied. On-chip DC blocking capacitors simplify system integration. Besides, it is available mounted in a hermetic surface mount package or in die form.

There are some features of TQ9161 as follows: (1)broad bandwidth: 1 to 8 GHz; (2)min insertion loss: <2 dB; (3)attenuation range: >10 dB; (4)input/output VSWR:<2:1; (5)response time (10%-90%): <50 ns; (6)single power supply.

The following is about the absolute maximum ratings of TQ9161: (1)DC power supply: 16 V; (2)operating temperature: -55 to +85; (3)storage temperature: -55 to +150; (4)power dissipation: 1.5 W. Then is about the DC characteristics at 20 (TC): (1)DC power supply: +10 V min, +12 V typ and +15 V max; (2)DC supply current: 25 mA typ and 40 mA max; (3)power dissipation: 0.3 W typ and 0.6 W max; (4)control voltage range: +1 to 4 V.
