The EZRadioPRO family includes a complete line of transmitters, receivers, and transceivers allowing the RF system designer to choose the optimal wireless part for their application. The Si4032/31 offers advanced radio features including continuous frequency coverage from 240–930 MHz and adjustable output power of up to +20 dBm with the Si4032. The Si4030 offers frequency coverage from 900 to 960 MHz to support the Japanese frequency bands. The Si4032 delivers a maximum output power of +20 dBm programmable from +11 to +20 dBm in 3 dB steps. The Si4031/30 delivers a maximum output power of +13 dBm programmable from –8 to +13 dBm. The Si4032/31/30’s high level of integration offers reduced BOM cost while simplifying the overall system design. The Si4032’s Industry leading +20 dBm output power ensures extended range and improved link performance. Additional system features such as an automatic wake-up timer, low battery detector, 64 byte TX FIFO and automatic packet handling reduce overall current consumption and allow the use of lower-cost system MCUs. An integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost and size. The transmitter supports automated packet construction, allowing data to be streamed from the TX FIFO without external MCU support. The PA is single-ended to allow for easy antenna matching and low BOM cost. The digital transmit modulation and automatic PA power ramping ensure precise transmit modulation and reduced spectral splatter, ensuring compliance with FCC and ETSI regulations. The Si4030 is designed to ensure compliance with ARIB regulations. The Si4032/31/30 is designed to work with an MCU, crystal, and a few passives to create a very low-cost system. Voltage regulators are integrated on-chip, which allows for a wide range of operating supply voltage conditions from +1.8 to +3.6 V.
