Application Notes:
1. WBPA0003A
A. SMA Torque Wrench Selection
Always use a torque wrench with 5 ~ 6 inch-lb coupling torque setting for mating the SMA cables to the amplifier in WP-6
housing. Never use torque more than 8 inch-lb wrench for tightening the mating cable to the connector. Otherwise, the
permanent damage will occur to the SMA connectors of the amplifier. 8710-1582 (5 inch-lb) is one of the ideal torque wrench
choice from Agilent Technology.
B. DC Power Line Connection
Strip the insulation layer at the end of DC power supply wire. The stripped distance should be in the range of 0.100” to 0.200”.
The 24 ~ 26 American Wire Gauge wire is suitable. Wound the stripped terminal wire about 3/4 to 1 turn on the DC feed thru
center pin. Solder the wounded wire and the center pin together. Clean the soldering area by Q-tip with alcohol to remove the
flux and residue. Do not use larger soldering iron tip with more than 750 F temperature setting to solder the wire and pin. Too
high temperature tip can damage the DC feed thru!
Repeat the process to solder the DC return wire on the ground turret. Larger soldering iron tip and higher temperature setting
can be used for the soldering.
C. Mounting the Amplifier
Use three pieces of #4-40 with longer than 9/16” screws for mounting the amplifier on a metal-based chase or heat sink. A
piece of T-gon thermal film is needed in between the bottom of the PA and the heat sink to ensure the proper thermal
dissipation. The sufficient heat sink is required. Refer to AN-155 for more detail heat sink design. Flat and spring washers are
needed to prevent the screw loosening during the shock and vibration. Always use the appropriate torque setting of the power
screwdriver to mount them.
2. WPM0003F
D. Mounting the Amplifier
Use four pieces of #2-56 or M2.5 with longer than 3/8” screws for mounting the amplifier on a metal-based chase or heat sink.
A piece of T-gon thermal film is needed in between the bottom of the PA and the heat sink to ensure the proper thermal
dissipation. The sufficient heat sink is required. Refer to AN-155 for more detail heat sink design. Flat and spring washers are
needed to prevent the screw loosening during the shock and vibration. Always use the appropriate torque setting of the power
screwdriver to mount the amplifier.
Always be very careful to solder the RF and DC connections to the amplifier. Use 0.01” diameter soldering iron tip to solder the
connections. Do not touch any components of the amplifier.
