Description
Connect to Power Supply.
Matched RF Input.
When VREG is low, the device goes into sleep mode, reducing supply current to 1 uA. When VREG is
high (2.85 V), the device operates in its normal transmit mode. When high, VREG draws a bias current of
approximately 10 mA.
A Ground Referenced Capacitor. It should be connected to this node to reduce bias line noise (see
figure 8).
Switches Between High Power and Low Power Modes. When MODE is low (0 V), the device operates in
high power mode. When MODE is high (2.5 V), the device operates in low power mode.
Unmatched RF Output. These parallel outputs can be matched to 50 Ω using strip-line and shunt
capacitance. The power supply voltage should be connected to these pins through a choke inductor.
This power supply pin should be connected to the supply via a choke circuit (see Figure 8).
When STBY is low (0 V), the device operates in transmit mode. When the radio is receiving data, STBY
can be taken high (2.5 V), reducing supply current to 10 mA.
No Connect. Do not connect these pins.
Connected to Ground.
The exposed paddle should be soldered down to a low impedance ground plane (use multiple vias (at
least 9) to stitch together the ground planes) for optimum electrical and thermal performance.
