| S868T Vishay Telefunken BIPMIC(R) - Cascadable Silicon Bipolar Amplifier Electrostatic sensitive device. Observe precautions for handling. Applications General purpose 50 W gain block for narrow and broad band IF and RF amplifiers in commercial and industrial applications. The 50 W level allows directly to cascade this amplifier with minimal external circuitry, thus providing a simple, cost effective way to achieve high level amplification. Features D D D D Broadband amplification 50 W cascadable gain block High gain (19 dB @900 MHz) Low noise figure (2.9 db @900 Mhz) D High output level D Low cost surface mount plastic package D Few external components 2 1 94 9279 13 579 3 4 S868T Marking: 868 Plastic case (SOT 143) 1 = RF-output, 2 = Ground, 3 = RF-input, 4 = Ground Typical biasing configuration Absolute Maximum Ratings Tamb = 25_C, unless otherwise specified Parameter Device current RF input power Total power dissipation Junction temperature Storage temperature range Test Conditions Symbol Ibias Pin Ptot Tj Tstg Value 55 20 275 150 -65 to +150 Unit mA dBm mW C C Tamb 25 C Maximum Thermal Resistance Tamb = 25_C, unless otherwise specified Parameter Test Conditions Junction ambient on glass fibre printed board (25 x 20 x 1.5) mm3 plated with 35mm Cu Symbol RthJA Value 450 Unit K/W Document Number 85056 Rev. 3, 20-Jan-99 www.vishay.de * FaxBack +1-408-970-5600 1 (3) S868T Vishay Telefunken Electrical AC Characteristics Ibias = 45 mA, f = 900 MHz , Z0 = 50 W, Tamb = 25_C, unless otherwise specified Parameter Power gain 3 dB bandwidth Input VSWR Output VSWR Noise figure Intermodulation distortion Output power @1dB gain compression Device voltage Test Conditions Symbol Gp f3dB VSWR VSWR F IM3 P-1dB Vd Min 17 Typ 19 0.5 1.8:1 1.8:1 2.9 55 13 5 Max Unit dB GHz f = 0.1 to 2.5 GHz f = 0.1 to 2.5 GHz f = 900 MHz 22.5 mV input voltage dB dB dBm V Dimensions of S868T in mm 96 12240 www.vishay.de * FaxBack +1-408-970-5600 2 (3) Document Number 85056 Rev. 3, 20-Jan-99 S868T Vishay Telefunken Ozone Depleting Substances Policy Statement It is the policy of Vishay Semiconductor GmbH to 1. Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances ( ODSs ). The Montreal Protocol ( 1987 ) and its London Amendments ( 1990 ) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency ( EPA ) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay-Telefunken products for any unintended or unauthorized application, the buyer shall indemnify Vishay-Telefunken against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
