Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Specification for packaged product only.
Supply current and output power are a function of the voltage input on the PC (power control) pin. All specifications in the “Electrical Charac-
teristics” table applies for condition VPC = 350mV. Increasing the voltage on the PC pin will increase transmit power and also increase MARK
supply current. Refer to the graphs “Output Power Versus PC Pin Voltage” and “Mark Current Versus PC Pin Voltage.”
Output power specified into a 50Ω equivalent load using the test circuit in Figure 2.
The MICRF102 was tested to be compliant to part 15.231 for maximum allowable TX power. The transmitted power is measured 3 meters
from the antenna using transmitter board TX102-2A in Figure 1. Measurement results are summarized in Table 1.
The Varactor capacitance tuning range indicates the allowable external antenna component variation to maintain tun-over-normal production
tolerances of external components. Guaranteed by design, not tested in production.
