1 Description
The TRF0206-SP evaluation module (EVM) is used to evaluate the TRF0206-SP device, which is a single-ended
input to differential output radiation hardened RF amplifier available in a 6.00 mm × 6.10 mm
2
, 12-pin LCC-FC
package. The device is designed to drive a high-speed differential input ADC without using a passive balun.
The board is set up for 50-Ω single-ended input matching. The amplifier has a low output impedance. The board
has ac-coupling capacitors at the input and output. The EVM is ready to connect to a +3.3-V power supply,
signal source, and test instruments for the measurements.
1.1 Features
• Operates on a 3.3-V supply.
• Designed for a single-ended 50-Ω input matching.
• Simple interface to the inputs and output through onboard SMA connectors.
• Power down option is available onboard using a jumper connector.

1.2 General Usage Information
This section provides general usage information for the TRF0206-SP EVM.
shows a general single
tone setup diagram as a reference point for the following instructions (some components, such as supply bypass
capacitors, are omitted for clarity):
1. Recommended power up sequence:
a. Before connecting the power-supply cables to the EVM, set the DC output power supply to +3.3 V.
b. Set the current limit of the DC output power supply at 250 mA.
c. Turn off the supply then connect the power supply cables to the J1 connector of the EVM.
d. Now turn on the DC power supply of VCC = +3.3 V. The supply current (I
Q
) drawn from the power supply
should be approximately 135 mA.
e. If the supply current is low, then ensure that the device is not disabled by the PD pin.
2. Power-down option:
a. C1.8 V (logic-1) on the PD pin to power-down the chip. Ground the PD pin to enable the chip.
