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.
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 V
= 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 50
equivalent load using the test circuit in Figure 5.
Transmitted power measured 3 meters from the antenna using transmitter board TX102-2A in Figure 6.
The Varactor capacitance tuning range indicates the allowable external antenna component variation to maintain tune over normal production
tolerances of external components. Guaranteed by design not tested in production.
When the device is first powered up or it loses power momentarily, it goes into the calibration mode to tune up the transmit antenna.
After the release of the STDBY, the device requires an initialization time to settle the REFOSC and the internal PLL. The first MARK state
(ASK HIGH) after exit from STDBY needs to be longer than the initialization time. The subsequent low to high transitions will be treated as
data modulation whereby the envelope transition time will apply.
Note 10.
The MICRF102 was tested to be Compliant to Part 15.231 for maximum allowable TX power, when operated in accordance with a loop
antenna described in Figure 6.
