2.1 General Usage Information

This section provides general usage information for the TRF2001PEVM. See Figure 2-1 for single tone setup for TX path enabled mode and Figure 2-2 for single tone setup for RX path enabled mode as reference setups for the following instructions (some components, such as supply bypass capacitors, are omitted for clarity):

  1. Recommended power up sequence:
    1. Set VOLT_PA_supply to 3.3V and current limit to 900mA.
      • Connect the power supply at J1.17 (VOLT_PA_supply) and J1.18 (GND).
      • Connect power supply sense lines at J1.19 (VOLT_PA_supply) and J1.20 (GND).
    2. Set VOLT_3P3V_supply to 3.3V and current limit to 100mA.
      • Connect the power supply at J1.21 (VOLT_3P3V_supply) and J1.22 (GND).
      • Connect power supply sense lines at J1.23 (VOLT_3P3V_supply) and J1.24 (GND).
    3. Set operating mode (TX path enabled, RX path enabled, or power down) using the jumpers at J1. See Table 2-1 for configuring the operating modes.
    Table 2-1 Jumper Configuration for Setting the Operating Mode

    		 Comment

    TX path enabled

    Use a jumper to connect:

    • J1.3 (CTL0/CEN) to J1.1 (VCC_3P3V)
    • J1.8 (CTL1/CIB) to J1.6 (VCC_3P3V)
    • J1.11 (CTL2/CTR) to J1.9 (VCC_3P3V)

    With no RF input at PA_IN, approximately 58mA current is expected at VOLT_PA_supply (VCC_PA), and approximately 7mA at VOLT_3P3V_supply (VCC).

    RX path enabled

    Use a jumper to connect:

    • J1.3 (CTL0/CEN) to J1.1 (VCC_3P3V)
    • J1.8 (CTL1/CIB) to J1.6 (VCC_3P3V)
    • J1.11 (CTL2/CTR) to J1.13 (GND)

    With no RF input at ANT, 0.3mA current is expected at VOLT_PA_supply (VCC_PA), and approximately 10mA at VOLT_3P3V_supply (VCC).

    Power down

    Use a jumper to connect:

    • J1.3 (CTL0/CEN) to J1.5 (GND)
    • J1.8 (CTL1/CIB) to J1.10 (GND)
    • J1.11 (CTL2/CTR) to J1.13 (GND)

    Device in powered down state
  2. Power-down sequence:
    1. Turn OFF RF signals to the TRF2001PEVM (PA_IN and ANT connectors).

    2. Set VOLT_3P3V_supply to 0V and then set VOLT_PA_supply to 0V.
