STMicroelectronics TSH690 40MHz‑to‑1GHz Amplifier Handbook
The TSH690 is a wide‑band RF amplifier covering 40 MHz to 1 GHz, offering up to 28 dB gain at 450 MHz and 21 dB gain at 900 MHz with adjustable output power above 20 mW. It can be biased for Class A, A‑B, or power‑down operation via the Vbias pin, making it suitable for ISM transmitters, cellular phone drivers, remote controls, and other wide‑band applications.
The handbook includes electrical characteristics, absolute maximum ratings, pin connections, package information, schematic diagrams, dissipation calculations, and detailed PCB layout recommendations. Mechanical dimensions of the plastic micropackage (SO) and ordering information are also provided.
