SC1894

225MHz to 3800MHz RF Power

Ampliﬁer Linearizer (RFPAL)

General Description

Features

The SC1894 is the Scintera 3rd generation of RF PA lin-

earizers (RFPAL™) that provide improved correction and

functionality over the previous generations. The SC1894

is a fully adaptive, RFin/RFout predistortion linearization

solution optimized for a wide range of amplifiers, power

levels, and communication protocols. The SC1894 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 SC1894

to operate over wide-signal bandwidths and consume

very low power.

● RFin/RFout PA Linearizer SoC in Standard CMOS

• Fully Adaptive Correction

• Up to 28dB ACLR and 38dB IMD Improvement

● External Reference Clock Support:

• 10, 13, 15.36, 19.2, 20, 26, and 30.72MHz

● Low Power Consumption:

• Duty-Cycled (9%) Feedback: 600mW

• Full Adaptation: 1200mW

● Frequency Range: 225MHz to 3800MHz

● Input Signal Bandwidth: 1.2MHz to 75MHz

● Packaged in 9mm x 9mm QFN Package

● Operating Case Temperature: -40°C to +105°C

● Fully RoHS Compliant, Green Materials

● Dual-RF Power Measurement

The SC1894 goes beyond linearization and provides

accurate RF power measurement of RFIN and RFFB.

Design support features including spectral monitoring

and ACLR alarm are also available. These design sup-

port features are accessed through the SC1894’s serial

peripheral interface (SPI) bus.
