general description the sc2200 belongs to the 4th-generation family of rf pa linearizers (rfpal) that provides increased integration and functionality over the previous generations. the device is a dual-path linearizer that is a fully-adaptive, rfin/rfout predistortion linearization solution optimized for a wide range of amplifiers, power levels, and communication protocols. it supports 2g to 4g standards (fdd and tdd) from 698mhz to 2700mhz as well as an expanded range of signal bandwidths from 60mhz down to 1.2mhz. the sc2200 accepts single- ended rf signals to eliminate baluns and features a mirrored pinout facilitating design of both paths. the device uses the pa output and input signals to adaptively generate an optimized correction function to minimize the pas distortion. using rf-domain analog signal processing enables the sc2200 to operate over wide bandwidths and with very low power consumption. the dual linearizer is optimized for high-performance mimo applications, including small cells, active antenna, and distributed antenna systems. applications cellular infrastructure ? single/multicarrier, multistandard: cdma/evdo, td-scdma, wimax, wcdma/hsdpa, lte, and td-lte ? bts ampliiers, rrh, booster ampliiers, repeaters, small cells, microcells, picocells, das, aas and mimo systems wide range of pas and output power ? ampliier: class a/ab, doherty ? average pa output power examples: cellular infrastructure: 27dbm to 40dbm ? pa process: ldmos, gan, hbt, gaas and ingap beneits ease of use ? integrated rfin/rfout solution smaller total system form factor (24mm x 26mm) reduces system power consumption and opex reduces bom costs and total volume ? smaller power supply, heat sink, and enclosure ? lower back-off reduces transistor costs features frequency range: 698mhzC2700mhz integrated preamp and single-ended rf i/os single +1.8v supply voltage external reference clock support: ? 10, 13, 15.36, 19.2, 20, 26, and 30.72mhz packaged in 11mm x 11mm sawn qfn package operating case temperature: -40c to +100c rohs, green, reach, and iso9001 compliant dual-path rfin/rfout linearizer in cmos soc fully adaptive correction up to 28db aclr and 38db imd improvement (1) 1.2mhz < bwsig 60mhz power consumption: ? duty-cycled (10%) feedback: 1500mw (dual-path) ? 100% adaptation: 1.95w (dual-path) ordering information and block diagram appears at end of data sheet.19-7748; rev 1; 6/16 sc2200 dual rf power ampliier linearizer (rfpal) downloaded from: http:///

detailed description introduction to predistortion using the sc2200 wideband signals in todays telecommunications systems have high peak-to-average ratios and stringent spectral regrowth specifications. these specifications place high linearity demands on power amplifiers. linearity can be achieved by backing off output power at the price of reduc - ing efficiency. however, this increases the component and operating costs of the power amplifier. better linearity can be achieved through the use of digital predistortion and other linearization techniques, but many of these methods are time consuming and costly to implement. the sc2200 is a true rfin and rfout solution where the complex signal processing is done in the rf domain, supporting modular power amplifier designs that are inde - pendent of the baseband and transceiver subsystems. this simple system-on-chip offers wide signal bandwidth, broad frequency of operation, and very low power con - sumption. it reduces development costs and speeds time to market. applicable across a broad range of signals including 2g, 3g, 4g wireless, and other modulation typesthe powerful analog signal processing engine is capable of linearizing the most efficient power amplifier topologies. the sc2200 delivers the required efficiency and performance demanded by todays wireless systems. wireless service providers are deploying networks with wider coverage, greater subscriber density, and higher data rates. these networks require more efficient power amplifiers. additionally, the emergence of mimo, distrib - uted architectures, and active antenna systems is driving the increased need to support smaller, more-efficient power amplifier implementations. furthermore, a strong push continues toward reducing the total capital and oper - ating costs of base stations. line top mark description 1 + indicates the part is lead (pb)-free and designates location of pin one/ball a1pb-free laser mark 2 sc2200 product part number 2 a product revision 2 -00 product coniguration: -00 = dual-rfpal base coniguration 3 yy date codeyear 3 ww date codework week 3 $$ indicates the package revision code from the reliability database 4 ### indicates the last 3 numeric characters from the lot number 4 @@ indicates the irst 2 alpha characters after the numeric characters from the lot number s c 2 2 0 0 a - 0 0 y y w w $ $ # # # @ @ + optional notes: maxim integrated marking standards specification reference: 20-0400. tm sc2200 dual rf power ampliier linearizer (rfpal) www.maximintegrated.com maxim integrated 8 top mark downloaded from: http:///
