The ITM-9139 SIP module is designed for 915MHz ISM band wireless applications using AMICCOM’s A7139 FSK/GFSK transceiver chipset. This compact module features a fully programmable frequency synthesizer by SPI interface. The maximum data rate is up to 100kbps (by using 12.8MHz crystal, or 250kbps by using 16MHz crystal)

ITM-9139 is optimized for very low power consumption. In addition, it can offer a very good link budget with a high efficient class-E power amplifier up to 16dBm and a low phase noise receiver. Therefore, ITM-9139 is very suitable for battery powered application with a nice LOS (line-of-sight) wireless range.
