MGA-14516 high gain, high linearity active bias low noise ampli?er data sheet description avago technologies MGA-14516 is a two stage, easy-to- use gaas mmic low noise ampli?er (lna) with active bias. the lna has low noise with good input return loss and high linearity achieved through the use of avago technologies proprietary 0.5um and 0.25um gaas en- hancement-mode phemt process. both lnas have an extra feature inside that allows a designer to adjust supply current. the ?rst stage has an additional feature where the gain can be adjusted externally without a?ecting noise ?gure. minimum matching needed for input, output and the inter-stage between the two lna. it is designed for optimum use between 1.4ghz to 2.7ghz. for optimum performance at lower frequency from 400mhz to 1.5ghz, the mga-13516 is recommended. both mga-13516 & MGA-14516 share the same package and pinout. pin con?guration and package marking 4.0 x 4.0 x 0.85 mm 3 16-lead qfn pin 1 pin 2 pin 3 pin 4 pin 1 6 pin 1 5 pin 1 4 pin 13 pin 12 pin 11 pin 10 pin 9 pin 5 pin 6 pin 7 pin 8 1 45 1 6 yyww xxxx top view botto m view notes: package marking provides orientation and identi?cation 14516 is the product identi?cation, yyww is the date code, xxxx is the last 4 digits of the lot number. features low noise ?gure high gain good irl high linearity performance high reverse isolation externally adjustable supply current externally adjustable gain gaas e-phemt technology [1] low cost qfn package excellent uniformity in product speci?cations speci?cations 1.95ghz ; q1 : 5v, 45ma (typ) q2 : 5v, 110ma 31.7 db gain 0.68 db noise figure 13 db irl 38 dbm output ip3 23.5 dbm output power at 1db gain compression applications low noise ampli?er for cellular infrastructure including gsm, cdma, w-cdma, td-scdma and wimax. other very low noise applications. note: 1. enhancement mode technology employs positive vgs, thereby eliminating the need of negative gate voltage associated with conventional depletion mode devices. pin descr i pt i o n pin descr i pt i o n 1 not used 9 not used 2 nc 10 rfout 3 rfin 11 rfout 4 rfgnd1 12 not used 5 vbias1 13 vg 6 fb1 14 rfgnd2 7 rfout1 15 vm 8 rfin2 16 vbias [1] [3] [ 4 ] 5 ] 6 ] 7 ] 8 ] [2 ] [ ] [0 ] [9] [ 6 ] [1 5 ] [1 4 ] [13] [2] q2 q1 atte n t i o n : o bserve precaut i o n s for ha n dl in g electrostat i c se n s i t i ve dev i ces. esd machine model = 40 v esd human body model = 200 v refer to avago application note a004r: electrostatic discharge, damage and control.
