What is the typical power consumption of the Synthesizer?
For the Si4133, when RF and IF are operating, typical current is 18 mA (See device datasheet Table 3). To calculate power consumption, multiply the current by the operating voltage. Typical power consumption is 3.0 v * 18 mA = 54 mW
When the Synthesizer is powered down, typical current consumption is approximately 1 uA and power consumption is 3 uW.
