A couple of things things are worth noting :
- None of the chips do both 800/900 and 2400 MHz
- Transmit current is lower than recieve current for most devices. In wonder why.
- The Ember chip is identical to the Chipcon chip. The pinout and the tekst of the datasheets are almost identical.
- The OKI and CompXS chips are identical.
