Hi,
in the MAX2829 datasheet it is said that the output power has a control range of 30dB. How are these 30 dB composed of the bbGain [0,2] and the rfGain [0,63] ?

The Tx RF gain covers about 30dB, with digital 0 mapping to the lowest gain. The full span of [0,63] is mapped linearly-in-dB over the 30dB range. See the middle plot on pg. 17 of the datasheet for details. The Tx BB gain covers just 5dB range, with 0 mapping to the lowest gain. See the two LSB of register 0x9 (Table 17 on pg. 36 of the datasheet) for details.

Hi.
Any idea what has to be the received signal strength that node will still receive packet successfully ? (~min&max)

I don't know the range of Rx power off hand, though it's something we're hoping to characterize for an upcoming reference design. The tricky part is that it depends on a lot of parameters. For example, if enough energy is received that a short QPSK packet could be decoded, but the packet detector doesn't trigger, the packet will still fail.

Hi.
I was thinking its bit tricky to characterize. Hopefully you guys will get some values...
