CPC7581MATR is a vector signal transceiver, specifically designed for cellular standards, consisting of RF transceiver, baseband modem FW and protocol stack for 3G and 4G. It is a powerful, multi-protocol and multi-band RFFrontend for Radio Access Network (RAN), utilizing a single chip and making complete radio access network.

The application fields of CPC7581MATR are 4G/LTE and 4G/LTE-A base stations and user devices, backhaul of TD-LTE, and IoT/M2M applications. It supports both TDD and FDD operation on all channels, and is compliant with 3GPP standards.

The working principle of CPC7581MATR is based on a single chip architecture. It consists of an RF transceiver, a baseband modem, and a protocol stack. The internal architecture, consists of digital interface, RF and baseband modem.

The RF transceiver module of CPC7581MATR performs the downlink (DL) and uplink (UL) modulation schemes; it supports modulation schemes such as OFDM/SC-FDMA/TD-SCDMA and etc. The uplink is done on the LTE/GPRS/EDGE/TD-SCDMA/W-CDMA/HSPA/CDMA2000/TD-LTE bands, where the downlink follows the 3GPP based modulation.

The baseband modem module of CPC7581MATR is a multi-protocol baseband modem, which supports communication for cellular standards. It consists of the processing architectures for macro base station control and switching, relaying and traffic channel decoding, coding, demodulation, modulation and decoding. It supports multiple protocol types such as GPRS, EDGE, W-CDMA and HSPA+.

The protocol stack of CPC7581MATR consists of interfaces between conventional protocols and the hardware. The protocol stack of CPC7581MATR is multi-protocol compatible and contains various hardware functions such as authentication, security, signaling and control protocols. This enables the device to provide support for multiple services and different access services.

At the same time, CPC7581MATR also supports multi-band operations on channels such as W-CDMA 900/1800, TD-SCDMA, GSM850/900/1800/1900, LTE-FDD 1800/2600/900/800/700/600/2100/1900/850/1700, LTE-TDD 2300/2500/2600/1800. Furthermore, it supports TDD operation on all channels including 3GPP, which ensures users have easy access to different networks.

In conclusion, CPC7581MATR is a powerful vector signal transceiver specifically designed for cellular standards, such as 4G/LTE and 4G/LTE-A base stations and user devices, backhaul of TD-LTE, and IoT/M2M applications. It consists of RF transceiver, a baseband modem, and a protocol stack, making it capable of multi-protocol, multi-band operation.
