说明

The THS7530 is fabricated using Texas Instruments' state-of-the-art BiCom III SiGe complementary bipolar process. The THS7530 is a dc-coupled, wide bandwidth amplifier with voltage-controlled gain. The amplifier has high-impedance differential inputs and low-impedance differential outputs with high bandwidth gain control, output common-mode control, and output voltage clamping.

Signal channel performance is exceptional with 300-MHz bandwidth, and third harmonic distortion of –61 dBc at 32 MHz with 1-V_PP output into 400  .

Gain control is linear in dB with 0 V to 0.9 V varying the gain from 11.6 dB to 46.5 dB with 38.8-dB/V gain slope.

Output voltage limiting is provided to limit the output voltage swing, and prevent saturating following stages.
