I need a 415 MHz transmitter for operation in countries requiring both EN 300 224 and EN 300 219. The main issue seems to be adjacent channel power.
For a device operating on 25 kHz channels, the total power in each adjacent channel must be -70 dBc.
For a device operating on 12.5 kHz channels it must be -60 dBc.
ADF7021 datasheet only references EN 300 220 and that isn’t good enough.
Does ADI offer a Tx which meets these requirements?
TI CC1070 doesn't seem to meet these requirements.
