SC1889 – 2nd Generation RF PA Linearizer
Static & Dynamic Waveforms, 5W ≤ PAout ≤ 60W
The SC1889 is Scintera’s 2nd generation RF PA linearizer (RFPAL) providing increased ACLR performance over the previous SC1887 as well adding support for EVDO, TD-SCDMA, WiMAX, HSDPA, LTE and TD-LTE waveforms. The SC1889 also supports multi-carrier and multi-standard waveforms with up to 60 MHz of instantaneous signal bandwidth. The SC1889 is a fully-adaptive, RFin / RFout predistortion linearization solution optimized for Class A/AB and Doherty power amplifiers operating at an average power level of 5W to 60 W. The SC1889 is ideal for use in traditional in-cabinet BTS amplifiers, RRU , tower mounted power amplifiers, microwave repeaters, booster amplifiers, microcells, picocells, DAS, AAS and MIMO systems.
Applications:
- Cellular infrastructure including small cells and microwave point-to-point (P2) / backhaul
- RRU, tower mounted power amplifiers, microwave repeaters, booster amplifiers, microcells, picocells, DAS, AAS and MIMO systems
- 5W ≤ PAout ≤ 60W – Note: Higher power possible depending on spectral emissions mask (SEM) limits
- CDMA, WCDMA, EVDO, TD-SCDMA, WiMAX, HSDPA, LTE and TD-LTE
- Other applications
- Software defined radios (SDR), HMS/Mobile military communications and white space
- Public safety mobile and portable transmitters
- Customer Premises Equipment (CPE)
- Class A/AB and Doherty amplifiers
- LDMOS, GaN, GaAs amplifiers
