... High (FSK mode): High frequency The Standby Input Pin selects active or low power shutdown/standby mode: If this pin unconnected or logic low, the TXC100 is placed in low current standby mode. If this pin is logic high, the TXC100 is in active mode and ready to transmit 4 Stdby Note: Lowest current consumption is achieved when all configuration pins are logic low. ...

... ES Out output, as close as possible to the TXC100 IC to minimize circuit parasitics. The power amplifier side of the resistor should be bypassed with 680 pF and 220 pF capacitors in parallel, as close to the resistor as possible. Power Amplifier - the power amplifier is an open-drain, Class C amplifier designed for a load impedance at PA ohms ...

... Output Matching When properly matched, the TXC100 can output up to +12 dBm into a 50Ω load. The output is an open-drain configuration which requires a pull-up inductor for biasing. The pull-up inductance serves to provide biasing for the power amplifier and is a high frequency choke to reduce unwanted coupling back into the power supply. Maximum power transfer occurs when the output is closely matched to 250Ω ...

... The capacitor may be a variable type or several fixed values may be attempted until an optimal match is reached. The use of a good network analyzer is essential for proper matching and maximum power transfer.
