TSH690 Datasheet | STMicroelectronics

DESCRIPTION TSH690 is a wide band RF amplifier, consisted of 2 stages, designed in advanced bipolar process featuring 28d B gain and +13.5d Bm output power at 450MHz under 3V. The pin 8 allows an external bias current adjust to tune the output power and also to set the amplifier in power-down mode. This powerful amplifier is dedicated to equip secured RF data transmitters as antenna drivers in ISM band (reliable RF meter-reading systems, secured Remote Controls, Cordless Telephones, ...)
