MAX2690 - Low-Noise / 2.5GHz Downconverter Mixer

General Description

The MAX2690 is a miniature, low-noise, low-power downconverter mixer designed for use in portable consumer 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.

MAX2690 19-1282; Rev 0; 10/97 EVAALVUAAILTAIOBNLEKIT Low-Noise, 2.5GHz Downconverter Mixer _______________General Description The MAX2690 is a miniature, low-noise, low-power downconverter mixer designed for use in portable consumer 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 compatibility with applications using differential IF filters, such as CDMA cellular phones.
