Part Number: CC1101-CC1190EM869RD
Other Parts Discussed in Thread: CC1101, CC1190, CC110L, CC1120, CC1121

Hi,

For the combination of CC110L-CC1190, what might be the worst case current consumption for maximum power output?

Regards

    I would assume that this would be in the same range as for CC1101 + CC1190:

    Its given 138mA for 20dBm.
    But we can transmit upto 27mA, i suppose?
    Assume this as the worst case, what might be the current consumption?

    The output power is limited to ~20 dBm due to the phase noise if you measure according to 300 220 v2.4.1 (ref the CC1101 - CC1190 app note). It could be that the output power could be higher if measuring according to v3.1.1.

    You will get an indication on the power consumption in www.ti.com/.../swra393. Note that you can adjust for CC1120 vs CC110L by checking the datasheet for both and add/ subtract the difference.

    Please note that the CC1101-CC1190 design has been designed for max +20 dBm. Even if you program CC1101 to the maximum you will not get more than approx +20 dBm out of the CC1190. The CC1120-CC1190 ref design, however, has been designed for operation up to +27 dBm. The reason why CC1101-CC1190 was limited to +20 dBm at the time was due to the modulation bandwidth requirements under EN300 220 V2.4.1. For higher output power than +20 dBm I would recommend CC1121 or CC1120 (CC1121 is a cheaper option than CC1120 and the only difference is that the minimum RX filter BW for CC1121 is limited to 42 kHz)
