agilent ada-4643 silicon bipolar darlington amplifier data sheet description agilent technologies ada-4643 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 struc- ture provides inherent broad bandwidth performance, result- ing in useful operating frequency up to 2.5 ghz. this is an ideal device for small-signal gain cascades or if amplification. ada-4643 is fabricated using agilents hp25 silicon bipolar process, which employs a double- diffused single polysilicon process with self-aligned submicron emitter geometry. the process is capable of simulta- neous high f t and high npn breakdown (25 ghz f t 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. features small signal gain amplifier operating frequency dc ?2.5 ghz unconditionally stable 50 ohms input & output flat, broadband frequency response up to 1 ghz operating current: 20 to 60 ma industry standard sot-343 package lead-free option available specifications 900 mhz, 3.5v, 35 ma (typ.) 17 db associated gain 13.4 dbm p 1db 28.3 dbm oip 3 4 db noise figure vswr < 2.2 throughput operating frequency single supply, typical i d = 35 ma applications cellular/pcs/wll base stations wireless data/wlan fiber-optic systems ism surface mount package sot-343 pin connections and package marking rfin 2tx gnd rfout & vd gnd note: top view. package marking provides orientation and identification. ?t? = device code ?? = date code character identifies month of manufacture. c block c block c bypass r c v cc = 5 v v d = 3.5 v rfc rf input rf output 2tx r c = v cc - v d i d typical biasing configuration attention: observe precautions for handling electrostatic sensitive devices. esd machine model (class a) esd human body model (class 1b) refer to agilent application note a004r: electrostatic discharge damage and control.
