I. Device Description
A. General
rd
The SC1894 is Scintera’s 3 generation of RF PA linearizers (RFPAL) providing 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 selfgenerated distortion and impairments. Using RF-domain analog 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. Advanced features
including spectral monitoring and ACLR alarm are also available. These optional features are accessed through the SC1894’s serial peripheral interface
(SPI) bus. The SC1894 is available in 9x9mm, 64 pin QFN package.

VI. Reliability Evaluation
A. Accelerated Life Test
The results of the 125°C biased (static) life test are shown in Table 1. Using these results, the Failure Rate, λ is calculated as follows:
λ =
MTTF
=
1
1.83
(Chi square value for MTTF upper limit)
1000 x 925 x 231 x 2
(where 925 = Temperature Acceleration factor assuming an activation energy of 0.7eV)
-9
= 4.28 x 10
= 4.28 F.I.T. (60% confidence level @ 25°C)
B. E.S.D. and Latch-Up Testing (Lot # A4222612401)
The SC1894A die type has been found to have all pins able to withstand a transient pulse of:
ESD-HBM: +/-1000V per JS-001-2012
ESD-CDM: +/- 250V per JEDEC JESD22-C101
Latch-Up testing has shown that this device withstands a current of +/-100mA, 85C and Power supply stress 1.5* VDDmax per
JEDEC JESD78D.
