________________General Desc ription
The MAX2430 is a versatile, silicon RF power amplifier
that operates directly from a 3V to 5.5V supply, making
it suitable for 3-cell NiCd or 1-cell lithium-ion battery
applications. It is designed for use in the 800MHz to
1000MHz frequency range and, at 915MHz, can pro-
duce +21dBm (125mW) of output power with greater
than 32dB of gain at V
CC
= 3.6V.
A unique shutdown function provides an off supply cur-
rent of typically less than 1μA to save power during
“idle slots” in time-division multiple-access (TDMA)
transmissions. An external capacitor sets the RF output
power envelope ramp time. External power control is
also possible over a 15dB range. The amplifier’s input
is matched on-chip to 50
. The output is an open col-
lector that is easily matched to a 50
load with few
external components.
The MAX2430 is ideal as a driver amplifier for portable
and mobile telephone systems, or as a complete power
amplifier for other low-cost applications, such as those
in the 915MHz spread-spectrum ISM band. It is fabri-
cated with Maxim’s high-frequency bipolar transistor
process and is available in a thermally enhanced,
16-pin narrow SO and miniature 16-pin PwrQSOP pack-
ages with heat slug.
