This section provides general usage information for the EVM.
- Power up procedure:
- Set the current limit of the DC power supply to 50mA.
- Set the voltage of the DC power supply between 1.8V and 3.3V.
- Verify that the supply is turned off.
- Connect the power supply cables to the J1 connector of the EVM.
- The positive supply rail from the DC power supply is connected to pin 1 of J1.
- Ground of DC output power supply is connected to pin 2 of J1.
- Connect a jumper between pins 2 and 3 of J2 to enable the TRF3302.
- Now turn on the DC power supply.
- The supply current (ICC) drawn from the power supply is approximately 4mA to 5mA.
- If the supply current is below 1mA, then verify that the device is not disabled with jumper at J2 connected between pins 1 and 2.
- Power-down procedure:
- Turn off the DC power supply.
See Figure 2-1 for a general single tone test setup diagram instruction. Note some components, such as supply bypass capacitors, are omitted for clarity.
- Single tone measurement setup recommendation:
- RF signal generator signal connected to the RF_IN(ANT) SMA connector of the EVM. Also, connect spectrum analyzer or RF power meter to RF_OUT SMA connector of the EVM.
- The RF signal generator used must support up to 1.6GHz signal frequency for testing out the EVM.
- The maximum input power to the TRF3302 is 10dBm at the RF_IN (ANT) SMA connector reference plane.
- Properly characterize and account for the insertion loss of RF coaxial (coax) cables to accurately measure the device's gain, NF, and linearity performance.
