It provides a complete set of features to ensure signal reliability and high-efficiency transmission, including frequency up-conversion, filtering, signal amplifying, signal detecting, programmable gain control, carrier acquisition and tracking, signal demodulating and decoding, and digital signal generation.

Application Field

The MT88L70ASR1 is suitable for a range of cellular network applications, such as GSM/GPRS, CDMA/WCDMA/TD-SCDMA, CDMA/WCDMA/HSPA, and LTE, as well as low-power WLAN IEEE802.11packet base stations, as it is able to support a variety of protocols and support the necessary signal conversion and processing.

Working Principle

The MT88L70ASR1 provides a suite of functions related to signal acquisition, processing, and transmission. Upon receiving an input signal, the chip will first perform frequency upconversion to convert the signal from low frequency to high frequency. After that, the signal is filtered, amplified, and detected by the necessary blocks on the chip. If the signal is detected to be valid, a gain control block will set the signal’s gain level to an optimal value. The chip then performs carrier acquisition, tracking, and demodulation of the signal, and finally performs digital signal decoding and error correction, if necessary.

Conclusion

The MT88L70ASR1 is an integrated signal reception and transmission chip for use in communication devices. It is suitable for a variety of applications, including cellular networks, base stations, and digital signal processing. It also includes a full set of features to ensure signal reliability and efficient transmission, relying on upconversion, filtering, amplifying, detecting, programmable gain control, carrier acquisition and tracking, demodulating, decoding and digital signal generation.
