A www.fairchildsemi.com Recommended turn-on sequence: 1. Connect common ground terminal to the Ground (GND) pin on the board. 2. Apply positive supply voltage VC1 (=3.4V) to pin VCC1 (first stage collector). 3. Apply positive supply voltage VC2 (=3.4V) to pin VCC2 (second stage collector). 4. Apply positive bias voltage VREF12 (=2.85V) to pin VREF (bias networks). 5. At this point, you should expect to observe the following positive currents flowing into the pins: Pin Current VREF12 7.0–9.0mA VCC1 50.0–60.0mA VCC2 70.0–80.0mA 6. Apply input RF power to SMA connector pin RFIN. Currents in pins VC1 and VC2 will vary depending on the input drive level. 7. Vary positive voltage on pin VREF12 from +2.85 V to +0 V to shut down the amplifier or alter the power level. Shut down current flow into the pins: Pin Current VCC1 <1nA VCC2 <1nA Recommended turn-off sequence: Use reverse order described in the turn-on sequence above. Note: 4. Turn on sequence is not critical and it is not necessary to sequence power supplies in actual system level design.

A www.fairchildsemi.com FMPA2300 2.3–2.4GHz WiMax/WiBro Linear Power Amplifier Evaluation Board Turn-On Sequence(4) CAUTION: THIS IS AN ESD SENSITIVE DEVICE. Solder Materials & Temperature Profile: Reflow soldering is the preferred method of SMT attachment. Hand soldering is not recommended. Precautions to Avoid Permanent Device Damage: • Cleanliness: Observe proper handling procedures to ensure clean devices and PCBs. Devices should remain in their original packaging until component placement to ensure no contamination or damage to RF, DC and ground contact areas. Reflow Profile • Ramp-up: During this stage the solvents are evaporated from the solder paste. Care should be taken to prevent rapid oxidation (or paste slump) and solder bursts caused by violent solvent out-gassing. A maximum heating rate is 3°C/sec. • Device Cleaning: Standard board cleaning techniques should not present device problems provided that the boards are properly dried to remove solvents or water residues. • Pre-heat/soak: The soak temperature stage serves two purposes; the flux is activated and the board and devices achieve a uniform temperature. The recommended soak condition is: 60-180 seconds at 150-200°C. • Static Sensitivity: Follow ESD precautions to protect against ESD damage: – A properly grounded static-dissipative surface on which to place devices. • General Handling: Handle the package on the top with a vacuum collet or along the edges with a sharp pair of bent tweezers. Avoiding damaging the RF, DC, and ground contacts on the package bottom. Do not apply excessive pressure to the top of the lid. • Reflow Zone: If the temperature is too high, then devices may be damaged by mechanical stress due to thermal mismatch or there may be problems due to excessive solder oxidation. Excessive time at temperature can enhance the formation of inter-metallic compounds at the lead/board interface and may lead to early mechanical failure of the joint. Reflow must occur prior to the flux being completely driven off. The duration of peak reflow temperature should not exceed 20 seconds. Soldering temperatures should be in the range 255–260°C, with a maximum limit of 260°C. • Device Storage: Devices are supplied in heat-sealed, moisture-barrier bags. In this condition, devices are protected and require no special storage conditions. Once the sealed bag has been opened, devices should be stored in a dry nitrogen environment. • Cooling Zone: Steep thermal gradients may give rise to excessive thermal shock. However, rapid cooling promotes a finer grain structure and a more crack-resistant solder joint. The illustration below indicates the recommended soldering profile. Device Usage: Fairchild recommends the following procedures prior to assembly. Solder Joint Characteristics: Proper operation of this device depends on a reliable void-free attachment of the heat sink to the PWB. The solder joint should be 95% void-free and be a consistent thickness. – Static-dissipative floor or mat. – A properly grounded conductive wrist strap for each person to wear while handling devices. • Assemble the devices within 7 days of removal from the dry pack. Rework Considerations: Rework of a device attached to a board is limited to reflow of the solder with a heat gun. The device should be subjected to no more than 15°C above the solder melting temperature for no more than 5 seconds. No more than 2 rework operations should be performed. • During the 7-day period, the devices must be stored in an environment of less than 60% relative humidity and a maximum temperature of 30°C • If the 7-day period or the environmental conditions have been exceeded, then the dry-bake procedure, at 125°C for 24 hours minimum, must be performed.
