Evaluates: SC1905SC1905 Evaluation Kit

General DescriptionThe SC1905 evaluation kits (SC1905-EVKs) provide the hardware and software graphical user interface (GUI) necessary for the evaluation of the SC1905. The SC1905 is a pin-compatible upgrade of the popular SC1894 RF PA linearizer (RFPAL) supporting signal bandwidths up to 100MHz. The SC1905 is a fully adaptive, RFin/RFout predistortion linearization solution optimized for a wide range of amplifiers, power levels, and communication protocols. The SC1905 uses the PA output and input signals to adaptively generate an optimized correction function in order to minimize the PA’s self-generated distortion and impairments. Using RF-domain analog signal processing enables the SC1905 to operate over wide-signal bandwidths and consume very low power.

Benefits ● Ease-of-Use

• Integrated RFin/RFout Solution• Reduces System Power Consumption, OPEX, and

Total BOM Costs• Smaller Power Supply, Heat Sink, and Enclosure• Lower Backoff Reduces Transistor Costs

Applications ● 4G and 5G Cellular Infrastructure

• Single/Multicarrier, Multistandard: WCDMA, LTE, and TD-LTE

• BTS Amplifiers, RRH, Booster Amplifiers, ● Repeaters, Small Cells, Microcells, Picocells, DAS,

AAS, and MIMO Systems ● Wide Range of PAs and Output Power

• Amplifier: Class A/AB and Doherty• PA Process: LDMOS, GaN, GaAs, and InGaP

● Any Application Requiring PA Linearization

Benefits and Features ● Frequency Ranges:

• SC1905-EVK3400: 3300MHz–3800MHz• SC1905-EVk2400: 2300MHz–2700MHz

● RFin/RFout PA Linearizer SoC in Standard CMOS• Fully Adaptive Correction

● External Reference Clock Support:• 10MHz, 13MHz, 15.36MHz, 19.2MHz, 20MHz,

26MHz, and 30.72MHz ● Low Power Consumption: 1280mW ● Frequency Range: 698MHz to 3800MHz ● Input Signal Bandwidth: 5MHz to 100MHz ● Packaged in 9mm x 9mm QFN Package ● Operating Case Temperature: -40°C to +105°C ● Fully RoHS Compliant, Green Materials ● Ease-of-Use

• Integrated RFin/RFout Solution• Reduced SW Development

● Reduces System Power Consumption and OPEX ● Reduces BOM Costs, Area, and Total Volume

• Smaller Power Supply, Heat Sink, and Enclosure• Small Implementation Size (< 6.5cm2)

Auxiliary Documentation ● SC1905 SPI Programming Guide is dedicated to

describing how the host communicates with the SC1905. It describes the communication protocol in addition to the addresses of all the variables and parameters for monitoring the status and configuration of the SC1905.

● The SC1905 Hardware Design Guide provides guidance on how to design the SC1905 into a system; for example, recommendations on PCB layout, regulator and delay line selection etc.

● The firmware release notes provide a comprehensive user’s guide to evaluate the SC1905 operation and performance with different power amplifiers.

These auxiliary documents are available on the SC1905 product web page on Maxim’s website.

#Denotes a RoHS-compliant device that may include lead(Pb) that is exempt under the RoHS requirements.
