_______________General Desc ription
The MAX2690 is a miniature, low-noise, low-power
downconverter mixer designed for use in portable con-
sumer equipment. Signals at the RF input port are
mixed with signals at the local-oscillator (LO) port using
a double-balanced mixer. The RF port frequency range
is 400MHz to 2500MHz. The LO port frequency range is
700MHz to 2500MHz. The IF frequency range is 10MHz
to 500MHz, provided the LO and RF frequencies are
chosen appropriately.
The IF port is differential, which provides good linearity
and low LO emissions, as well as providing compatibili-
ty with applications using differential IF filters, such as
CDMA cellular phones. The mixer noise figure is 10dB
at 900MHz.
The MAX2690 draws 16mA at V
CC
= 3V and operates
from a +2.7V to +5.5V supply. A logic-controlled shut-
down mode reduces the supply current to less than 1μA,
making it ideal for battery-operated equipment. This
device is offered in a miniature 10-pin μMAX package.
