package. This pad should be connected to the ground
plane of the board by using multiple vias under the
device to provide the best RF/thermal conduction path.
Solder the exposed pad on the bottom of the device
package to a PC board exposed pad.
The MAX2055 Evaluation Kit can be used as a refer-
ence for board layout. Gerber files are available upon
request at www.maxim-ic.com.
Power-Supply Bypassing
Proper voltage-supply bypassing is essential for high-
frequency circuit stability. Bypass each V
CC
pin with a
1000pF and 100pF capacitor. Connect the 100pF
capacitor as close to the device as possible. Resistor
R7 helps reduce switching transients. If switching tran-
sients are not a concern, R7 is not required. Therefore,
connect pin 9 directly to V
CC
.
Exposed Paddle RF Thermal
Considerations
The EP of the MAX2055
’
s 20-pin TSSOP-EP package
provides a low thermal-resistance path to the die. It is
important that the PC board on which the IC is mounted
be designed to conduct heat from this contact. In addi-
tion, the EP provides a low-inductance RF ground path
for the device.
It is recommended that the EP be soldered to a ground
plane on the PC board, either directly or through an
array of plated via holes.
Soldering the pad to ground is also critical for efficient
heat transfer. Use a solid ground plane wherever
possible.
