【产通社，7月26日讯】Semtech Corporation (Nasdaq: SMTC) 消息，其SX1232高性能、低电流sub-GHz RFIC收发器具有出色的电池寿命和链路稳健性，适合智能电表、安全系统、路由器接入、传感器网络和家用/建筑自动化等领域。

产品特点

SX1232 overcomes the typical conundrum of achieving high performance and low current consumption simultaneously.  The SX1232 delivers market leading performance for adjacent channel selectivity (54dB), sensitivity (-123dBm@1.2kbps), image rejection (48dB w/ 1% PER), and phase noise (-102dBc/Hz@10kHz, 915MHz) for significantly lower receive current (9.3mA) than competing devices.  In many applications the range is limited by IIP3 or the linearity of the receiver front-end caused by mixing products of strong out of band interferers. The SX1232 transceiver delivers ultra-low receive current without compromising the IIP3 performance.  With the highest gain and maximum sensitivity the IIP3 performance is -12dBm making it the most robust and reliable solution under any condition.

For applications requiring range the SX1232 offers an integrated +20dBm amplifier coupled with a sensitivity of -123dBm at 1.2kbps providing a typical link budget of 143dB.  This high link budget and ultra-fast frequency hopping time makes it ideal for frequency hopping applications as the SX1232 can scan the entire 902-928MHz band without ever exiting receive mode.  The synthesizer settling time of 20usec for a 1MHz frequency step and RSSI sampling capability on a fraction of a bit time makes it the fastest solution for frequency hopping applications. 

The SX1232 supports GFSK, FSK, GMSK, and OOK modulation and is designed to support WMBus, IEEE 802.15.4g (SUN), FCC 15.247, ARIB T96/108, EN 300-220 as well as other worldwide standards and regulations.  The SX1232 will be the basis for Semtech¹s future product line based on a new modulation scheme that will deliver four to eight times range advantage versus existing systems with a low cost bill of materials (BOM).
