Agilent ADA-4743 Silicon Bipolar Darlington Amplifier Data Sheet Features • Small Signal gain amplifier www.DataSheet4U.com Description Agilent Technologies’ ADA-4743 is an economical, easy-to-use, general purpose silicon bipolar RFIC gain block amplifiers housed in a 4-lead SC-70 (SOT-343) surface mount plastic package which requires only half the board space of a SOT-143 package. The Darlington feedback structure provides inherent broad bandwidth performance, resulting in useful operating frequency up to 2.5 GHz. This is an ideal device for small-signal gain cascades or IF amplification. ADA-4743 is fabricated using Agilent’s HP25 silicon bipolar process, which employs a doublediffused single polysilicon process with self-aligned submicron emitter geometry. The process is capable of simultaneous high fT and high NPN breakdown (25 GHz fT at 6V BVCEO). The process utilizes industry standard device oxide isolation technologies and submicron aluminum multilayer interconnect to achieve superior performance, high uniformity, and proven reliability. Surface Mount Package SOT-343 • Operating frequency DC – 2.5 GHz • Unconditionally stable • 50 Ohms input & output • Flat, Broadband Frequency Response up to 1 GHz • Operating Current: 40 to 80 mA • Industry standard SOT-343 package • Lead-free option available Specifications 900 MHz, 3.8V, 60 mA (typ.) • 16.5 dB associated gain • 17.1 dBm P1dB • 32.6 dBm OIP3 • 4.2 dB noise figure • VSWR < 2 throughput operating frequency • Single supply, typical Id = 60 mA Applications • Cellular/PCS/WLL base stations • Wireless data/WLAN • Fiber-optic systems VCC = 5 V Pin Connections and Package Marking RFout & Vd GND GND 3Tx RFin Note: Top View.
