MAX19985ETX+

RF Mixers Overview

The MAX19985ETX+ is a dual, silicon-germanium (SiGe) up/down converter designed for high-linearity RF applications. It operates within a radio frequency range of 700 MHz to 1 GHz and supports an intermediate frequency of 250 MHz. The device provides a gain of 7.5 dB with a P1dB compression point of 16.2 dBm and a noise figure of 10.5 dB. It functions on a 5 V supply with a current consumption of 400 mA, housed in a TQFN-EP-36 package.
