CAMARILLO, Calif.--(SX1232, a fully integrated, high performance, low current sub-GHz RF transceiver. The device offers significant advantages in range, battery life and link robustness in the presence of interference making it ideal for applications such as smart metering, security system, remote access, sensor networks and home/building automation.)--Semtech Corporation. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today expanded its RFIC platform with the new
“The SX1232 extends Semtech’s position as the performance and low power leader for RF transceivers. Delivering the longest range and the most robust link performance for the lowest power is the key focus for Semtech’s wireless product line”
The 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 conditions.
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 Semtech’s future product line based on a new modulation scheme that will deliver four to eight-times range advantage versus existing systems with a lower cost bill of materials (BOM).
“The SX1232 extends Semtech’s position as the performance and low power leader for RF transceivers. Delivering the longest range and the most robust link performance for the lowest power is the key focus for Semtech’s wireless product line,” said Alain Dantec, Senior Vice President of Wireless and Sensing Products.
