3.6V, 1W RF Power Transistors
for 900MHz Applications
General Description
The MAX2601/MAX2602 are RF power transistors opti-
mized for use in portable cellular and wireless equipment
that operates from three NiCd/NiMH cells or one Li-Ion
cell. These transistors deliver 1W of RF power from a
3.6V supply with efficiency of 58% when biased for con-
stant-envelope applications (e.g., FM or FSK). For NADC
(IS-54) operation, they deliver 29dBm with -28dBc ACPR
from a 4.8V supply.
The MAX2601 is a high-performance silicon bipolar RF
power transistor. The MAX2602 includes a high-
performance silicon bipolar RF power transistor, and a
biasing diode that matches the thermal and process
characteristics of the power transistor. This diode is
used to create a bias network that accurately controls
the power transistor’s collector current as the tempera-
ture changes.
The MAX2601/MAX2602 can be used as the final stage
in a discrete or module power amplifier. Silicon bipolar
technology eliminates the need for voltage inverters
and sequencing circuitry, as required by GaAsFET
power amplifiers. Furthermore, a drain switch is not
required to turn off the MAX2601/MAX2602. This
increases operating time in two ways: it allows lower
system end-of-life battery voltage, and it eliminates the
wasted power from a drain-switch device.
The MAX2601/MAX2602 are available in thermally
enhanced, 8-pin SO packages, which are screened to
the extended temperature range (-40°C to +85°C).
