The THS7530 device 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
Signal-channel performance is exceptional with
300-MHz bandwidth, and third harmonic distortion of –61 dBc at 32 MHz with
1-VPP output into 400 Ω.
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 to prevent
saturating following stages.
The device is characterized for operation over the industrial temperature range, –40°C to
