    &lt;p&gt;The STEVAL-IKR002V7D product evaluation board is based on the SPIRIT1, a very low-power RF transceiver intended for RF wireless applications in the sub 1 GHz frequency band. The STEVAL-IKR002V7D also features an on-board external front-end module from Skyworks(SKY66100-11), which can reach a maximum output power of 27 dBm (500 mW).&lt;/p&gt;
&lt;p&gt;The SPIRIT1 is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to operate at other additional frequencies in the 300-348 MHz, 387-470 MHz, and 779-956 MHz bands. The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220 standard.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Applications:&lt;/strong&gt;&lt;/p&gt;

    &lt;div class="xs-mt3"&gt;
    &lt;p&gt;The STEVAL-IKR002V7D product evaluation board is based on the SPIRIT1, a very low-power RF transceiver intended for RF wireless applications in the sub 1 GHz frequency band. The STEVAL-IKR002V7D also features an on-board external front-end module from Skyworks(SKY66100-11), which can reach a maximum output power of 27 dBm (500 mW).&lt;/p&gt;
&lt;p&gt;The SPIRIT1 is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to operate at other additional frequencies in the 300-348 MHz, 387-470 MHz, and 779-956 MHz bands. The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220 standard.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Applications:&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;AMR (automatic meter reading)&lt;/li&gt;
&lt;li&gt;Home and building automation&lt;/li&gt;
&lt;li&gt;WSN (wireless sensors network)&lt;/li&gt;
&lt;li&gt;Industrial monitoring and control&lt;/li&gt;
&lt;li&gt;Wireless fire and security alarm systems&lt;/li&gt;
&lt;li&gt;Point-to-point wireless link&lt;/li&gt;
&lt;/ul&gt;
    &lt;/div&gt;
    
        &lt;h3 class="toc-item xs-pb2 xs-border-bottom"&gt;Features&lt;/h3&gt;
    &lt;ul&gt;
&lt;li&gt;SPIRIT1 low power sub GHz transceiver in a standalone RF module tuned for 169 MHz, with external Skyworks front-end module(SKY66100-11).&lt;/li&gt;
&lt;li&gt;Modulation schemes: 2-FSK, GFSK, MSK, GMSK, OOK, and ASK&lt;/li&gt;
&lt;li&gt;Programmable air data rate: from 1 to 500 kbps&lt;/li&gt;
&lt;li&gt;Maximum output power: 27 dBm&lt;/li&gt;
&lt;li&gt;Excellent receiver sensitivity (-123 dBm)&lt;/li&gt;
&lt;li&gt;Suitable for wireless M-BUS applications&lt;/li&gt;
&lt;li&gt;Meets the tight narrow-band system requirements&lt;/li&gt;
&lt;li&gt;Low duty cycle RX/TX operation mode&lt;/li&gt;
&lt;li&gt;Automatic acknowledgment, retransmission, and timeout protocol engine&lt;/li&gt;
&lt;li&gt;AES 128-bit encryption co-processor&lt;/li&gt;
&lt;li&gt;SPI interface for microcontroller&lt;/li&gt;

    &lt;p&gt;The STEVAL-IKR002V7D product evaluation board is based on the SPIRIT1, a very low-power RF transceiver intended for RF wireless applications in the sub 1 GHz frequency band. The STEVAL-IKR002V7D also features an on-board external front-end module from Skyworks(SKY66100-11), which can reach a maximum output power of 27 dBm (500 mW).&lt;/p&gt;
&lt;p&gt;The SPIRIT1 is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to operate at other additional frequencies in the 300-348 MHz, 387-470 MHz, and 779-956 MHz bands. The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220 standard.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Applications:&lt;/strong&gt;&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;AMR (automatic meter reading)&lt;/li&gt;
&lt;li&gt;Home and building automation&lt;/li&gt;
&lt;li&gt;WSN (wireless sensors network)&lt;/li&gt;
&lt;li&gt;Industrial monitoring and control&lt;/li&gt;
&lt;li&gt;Wireless fire and security alarm systems&lt;/li&gt;
&lt;li&gt;Point-to-point wireless link&lt;/li&gt;
&lt;/ul&gt;
    &lt;/div&gt;
    
        &lt;h3 class="toc-item xs-pb2 xs-border-bottom"&gt;Features&lt;/h3&gt;
    &lt;ul&gt;
&lt;li&gt;SPIRIT1 low power sub GHz transceiver in a standalone RF module tuned for 169 MHz, with external Skyworks front-end module(SKY66100-11).&lt;/li&gt;
&lt;li&gt;Modulation schemes: 2-FSK, GFSK, MSK, GMSK, OOK, and ASK&lt;/li&gt;
&lt;li&gt;Programmable air data rate: from 1 to 500 kbps&lt;/li&gt;
&lt;li&gt;Maximum output power: 27 dBm&lt;/li&gt;
&lt;li&gt;Excellent receiver sensitivity (-123 dBm)&lt;/li&gt;
&lt;li&gt;Suitable for wireless M-BUS applications&lt;/li&gt;
&lt;li&gt;Meets the tight narrow-band system requirements&lt;/li&gt;
&lt;li&gt;Low duty cycle RX/TX operation mode&lt;/li&gt;
&lt;li&gt;Automatic acknowledgment, retransmission, and timeout protocol engine&lt;/li&gt;
&lt;li&gt;AES 128-bit encryption co-processor&lt;/li&gt;
&lt;li&gt;SPI interface for microcontroller&lt;/li&gt;
