we are designing an RF interface for the ISM 868-870 MHz band.
We are attracted to the S2-LP transceiver mainly because it drains only 10 mA at 10 dBm RF output power
I got a couple of questions about the S2-LP transceiver.
1. Does it support a TCXO?
If yes, what's the suggested frequency for the best phase noise performance?
2. Does a single chip "balun + conjugate match + harmonic filter" exist or at least planned for introduction by Q4 2017?
