- LTE Femtocell and Picocell Basestations
IQ mismatch of both RX and TX paths is factory calibrated to meet the EVM requirement for 64QAM modulation in select bands. In addition, the TX path does not require an external SAW filter to meet emission and desensitization specifications in some applications.
All decimation/interpolation and channel selection filters are included on chip. For data transmission to the BBIC, the transceiver includes a JESD207-compliant parallel interface. The device is controlled via a standard SPI interface.
