Notes:
1. Gain settled to within 90% of final value, DC settled to within 10% of desired signal’s final value.
2. TXD input signal 120 mVpp, 300 kHz sinusoidal, Rmod = 1.2 kΩ.
3. The specifications in Table 3 are guaranteed at a supply voltage (Vcc) of 3.6 V. At Vcc below 3.0 V, the RF105 is functional, but the system performance may be
degraded.
