2.2.1. Frequency and Frequency Bands
The RFpico board has an on-board antenna and RF matching to provide solutions for supported frequency bands.
A stand-alone antenna can also be used with the SMA connector.
Different RF matchings are required for each frequency band. The range test demo automatically reads frequency
band information out of the on-board EEPROM and selects the appropriate frequency range.
Si4x55 devices support the following three frequency bands:
Low band: 285–350 MHz
Middle band: 425–525 MHz
High band: 850–960 MHz
The EZRadio Two Way Link Development Kits are provided for the middle and the high bands; however, the range
test demo supports all the three bands. The demo can be used with low band RFpico boards as well.
The range test demo provides four different selectable frequencies in all the supported bands. Table 2. lists the
available frequencies.

2.2.2. Modulation
User can select from three types of modulation:
GFSK with high precision TX crystal (TX: 30 ppm, RX: 30 ppm)
GFSK (TX: 150 ppm, RX: 30 ppm)
OOK
2.2.3. Data Rate
The user can select from three different data rates. Table 3 lists the available data rates.
