The MAX2240 single-supply, low-voltage power amplifi-
er (PA) IC is designed specifically for applications in
the 2.4GHz to 2.5GHz frequency band. The PA is com-
pliant with Bluetooth, HomeRF, and 802.11 standards,
as well as other FSK modulation systems. The PA pro-
vides a nominal +20dBm (100mW) output power in the
highest power mode.
The PA includes a digital power control circuit to greatly
simplify control of the output power. Four digitally con-
trolled output power levels are provided: from +3dBm
to +20dBm. A digital input controls the active or shut-
down operating modes of the PA. In the shutdown
mode, the current reduces to 0.5µA.
The IC integrates the RF input and interstage matching
to simplify application of the IC. Temperature and sup-
ply-independent biasing are also included to provide
stable performance under all operating conditions.
The IC operates from a +2.7V to +5V single-supply volt-
age. No negative bias voltage is required. Current con-
sumption is a modest 105mA at the highest power
level.
The part is packaged in the ultra-chipscale package
(UCSP), significantly reducing the required PC board
area. The chip occupies only a 1.56mm x 1.56mm area.
The 3 x 3 array of solder bumps are spaced with a
0.5mm bump pitch.
