1) The output-frequency range can be increased by limiting the temperature and supply voltage
range.
Minimum fVCO − 1 MHz => Minimum Tamb + 5°C
Maximum fVCO + 1 MHz => Maximum Tamb − 5°C
Maximum fVCO + 1 MHz => Minimum VS + 25 mV, max. + 40 MHz.
2) Derating linearly to a saturation voltage of max. 140 mV at ICLKOUT = 0 mA
3) Matching circuitry as used in the 50 Ohm-Output Testboard for 434 MHz operation.
Tolerances of the passive elements not taken into account.
Range @ 2.1 V, +25°C: 2.4 dBm +/- 0.7 dBm
Typ. temperature dependency at 2.1 V: +0.4 dBm@-40°C and -1.4 dBm@+125°C, reference +25°C
Range @ 3.0 V, +25°C: 5.0 dBm +/- 1.0 dBm
Typ. temperature dependency at 3.0 V: +0.5 dBm@-40°C and -1.9 dBm@+125°C, reference +25°C
Range @ 4.0 V, +25°C: 6.6 dBm +/- 2.0 dBm
Typ. temperature dependency at 4.0 V: +0.6 dBm@-40°C and -3.1 dBm@+125°C, reference +25°C
4) Matching circuitry as used in the 50 Ohm-Output Testboard for 868 MHz operation.
Tolerances of the passive elements not taken into account.
Range @ 2.1 V, +25°C: 0.0 dBm +/- 1.0 dBm
Typ. temperature dependency at 2.1 V: +0.6 dBm@-40°C and -2.5 dBm@+125°C, reference +25°C
Range @ 3.0 V, +25°C: 2.0 dBm +/- 2.0 dBm
Typ. temperature dependency at 3.0 V: +0.9 dBm@-40°C and -3.6 dBm@+125°C, reference +25°C
Range @ 4.0 V, +25°C: 3.2 dBm +/- 2.7 dBm
Typ. temperature dependency at 4.0 V: +1.3 dBm@-40°C and -4.0 dBm@+125°C, reference +25°C
A smaller load impedance reduces the supply-voltage dependency.
A higher load impedance reduces the temperature dependency.
