SC1894-EVK1500

The SC1894-EVK1500 is a 1350MHz to 1800MHz RF power amplifier linearizer evaluation kit. 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 analogue signal processing enables the SC1894 to operate over wide-signal bandwidths and consume very low power. 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 optional design support are accessed through the SC1894’s serial peripheral interface (SPI) bus.

• 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 of 600mW (duty-cycled (9%) feedback), 1200mW (full adaptation)
• Input signal bandwidth: 1.2MHz to 75MHz
• Dual-RF power measurement
• Broadcast Infrastructure (SC1894A-00C13); Cellular Infrastructure (SC1894A-00C13); Microwave Backhaul (SC1894A-00M13); Wide Range of PAs and Output Power
