3.6V, 1W RF Power Transistors

for 900MHz Applications

Slug Layout Techniques

Applications Information

The most important connection to make to the

MAX2601/MAX2602 is the back side. It should connect

directly to the PC board ground plane if it is on the top

side, or through numerous plated through-holes if the

ground plane is buried. For maximum gain, this con-

nection should have very little self-inductance. Since it

is also the thermal path for heat dissipation, it must

have low thermal impedance, and the ground plane

should be large.

Optimum Port Impedance

The source and load impedances presented to the

MAX2601/MAX2602 have a direct impact upon its gain,

output power, and linearity. Proper source- and load-

terminating impedances (Z and Z ) presented to the

power transistor base and collector will ensure optimum

performance.

For a power transistor, simply applying the conjugate of

the transistor’s input and output impedances calculated

from small-signal S-parameters will yield less than opti-

mum device performance.

For maximum efficiency at V

= 0.75V and V

3.6V, the optimum power-transistor source and load

impedances (as defined in Figure 3) are:

At 836MHz: Z = 5.5 + j2.0

Z = 6.5 + j1.5

2.8nH

At 433MHz: Z = 9.5 - j2.5

Z = 8.5 - j1.5

and Z reflect the impedances that should be pre-

sented to the transistor’s base and collector. The pack-

age parasitics are dominated by inductance (as shown

in Figure 3), and need to be accounted for when calcu-

2.8nH

lating Z and Z .

The internal bond and package inductances shown

in Figure 3 should be included as part of the end-

application matching network, depending upon exact

layout topology.
