Basic Connections Power Supply The voltage supply on the ADL5571, which ranges from 3.2 V to 4.2 V, should be connected to the VCCx pins. VCC1 is decoupled with Capacitor C7, whereas VCC2 uses a tank circuit to prevent RF signals from propagating on the dc lines. RF Input Interface The RFIN pin is the port for the RF input signal to the power amplifier. The L3 inductor, 2.7 nH, matches the input impedance to 50 Ω. RFIN 2.7nH L3 6 Figure 20. RF Input with Matching Component RF Output Interface The parallel RF output ports have a shunt capacitor, C3 (2.7 pF), and the line inductance of the microstrip line for optimized output power and linearity. The characteristics of the ADL5571 are described for 50 Ω impedance after the output matching capacitor (load after C3). C4 provides dc blocking on the RF output.

However, during receive mode, the pin can be biased high (2.5 V) to shift the device into standby mode, which reduces current consumption to 9 mA. VREG Enable During normal transmit, the VREG pin is biased to 2.85 V and draws 9 mA of current. When the VREG pin is low (0 V), the device suspends itself into sleep mode (irrespective of supply biasing). In this mode, the device draws less than 1 μA of current. |
