♦ 7.6dBm Input Third-Order Intercept Point

♦ 10dB Downconverter Mixer Noise Figure

♦ 7.9dB Gain

The MAX2690 is a minia ture , low-nois e , low-p owe r

downconverter mixer designed for use in portable con-

s ume r e q uip me nt. Sig na ls a t the RF inp ut p ort a re

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.

♦ 400MHz to 2500MHz Wideband Operation

♦ Low Cost

♦ +2.7V to +5.5V Single-Supply Operation

♦ <1µA Shutdown Mode

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.

♦ Ultra-Small 10-Pin µMAX Package

The MAX2690 draws 16mA at V

= 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.
