rf to if dual downconverting mixer 3400mhz C3800mhz idt zero-distortion tm mixer 1 rev 1, december 2014 idtf1178nbgi datasheet g eneral d escription this document describes the specifications for the idtf1178 zerodistortion tm rf to if downconverting dual mixer. this device is part of a series of mix ers offered with high side and/or low side injection op tions for all utra bands. see the part# matrix for pin compatible & feature compatible devices in this ser ies. the f1178 dual channel device is designed to operat e with a single 5v supply. it is optimized for opera tion in a multimode, multicarrier basestation receiver fo r rf bands from 3400mhz 3800mhz with low side lo injection. if frequencies from 30mhz to 550mhz are supported. nominally, the device offers +37.5dbm output ip3 with 297ma of i cc . c ompetitive a dvantage in typical basestation receivers, the rf to if mixe r dominates the linearity performance for the entire receive system. the zerodistortion tm family of mixers dramatically improves the maximum signal levels (im 3 tones) that the bts can withstand at a desired sign al to noise ratio (snr). zerodistortion tm technology allows realization of either benefit. ip3 o : ? ?? ? 9db dissipation: ? ?? ? 23% noise figure: 8.5db p art # m atrix part# rf freq range (mhz) utra bands if freq range (mhz) typ. gain (db) injection f1100 698 - 915 5,6,8,12,13,14,17, 19,20 150 - 450 9.0 high side f1102 400 - 1000 5,6,8,12,13,14,17, 19,20 50 - 300 9.0 both f1150 1700 - 2200 1,2,3,4,9,10, 33, 34,35, 36, 37,39 50 - 450 8.5 high side f1152 1400 - 2200 1,2,3,4,9,10,11 1 , 21 1 , 24 1 , 33, 34,35, 36, 37,39 50 - 350 8.5 low side f f 1 1 1 1 6 6 2 2 2 2 3 3 0 0 0 0 C C 2 2 7 7 0 0 0 0 7 7 , , 3 3 8 8 , , 4 4 0 0 , , 4 4 1 1 5 5 0 0 C C 5 5 0 0 0 0 8 8 . . 9 9 b b o o t t h h f f 1 1 1 1 7 7 8 8 3 3 4 4 0 0 0 0 - - 3 3 8 8 0 0 0 0 2 2 2 2 , , 4 4 2 2 , , 4 4 3 3 3 3 0 0 - - 5 5 5 5 0 0 9 9 . . 0 0 l l o o w w s s i i d d e e 1 C with high side injection f eatures ? dual path for diversity systems ? ideal for multicarrier systems ? 9db gain ? ultra linear + + 3 3 7 7 . . 5 5 d d b b m m i i p p 3 3 o o ? ? 8.5db nf ? 200 output impedance ? high +11dbm p1db i ? p p i i n n & & f f e e a a t t u u r r e e c c o o m m p p a a t t i i b b l l e e ? 6mm x 6mm, 36pin package ? i i n n d d i i v v i i d d u u a a l l p p a a t t h h s s t t a a n n d d b b y y m m o o d d e e ? <400 nsec settling from power up ? i cc = 297ma d evice b lock d iagram o rdering i nformation idt f1178nbgi8 0.8 mm height package green industrial temp range tape & reel omit idt prefix rf product line
