Low-Noise, 2.5GHz Downconverter Mixer

Maxim Integrated 

Low-Noise, 2.5GHz

Downconverter Mixer

AC ELECTRICAL CHARACTERISTICS (continued)

(MAX2690 EV kit; VCC = +3.0V; PLO = -3dBm; PRF = -25dBm; SHDN = high; RFIN matched for 900MHz, 1.95GHz, and 2.45GHz as

noted below. Inductor connected from LGND to GND = 39nH for 900MHz operation, 27nH for 1.95GHz operation, and 6.8nH for

2.45GHz operation. TA = +25°C, unless otherwise noted.)

Note 1: Consult the Applications Information section for information on designing a matching network.

Note 2: Guaranteed by design and characterization.

Note 3: This spurious response is caused by a higher-order mixing product (2x2). Specified RF frequency is applied and IF output

power is observed at the desired IF frequency (200MHz for fRF = 900MHz, or 1.95GHz, and 350MHz for fRF = 2.45GHz).

Note 4: From the time SHDN goes high to the time ICC reaches 90% of its final value (on), or from the time SHDN goes low to the

time ICC drops below 10µA (off).
