... Rev 0; 10/97 _______________General Description 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 ...

... Low-Noise, 2.5GHz Downconverter Mixer ________________________________________________Key Specification Statistics (MAX2690 EV kit +3.0V -3dBm erwise noted.) Histograms represent measured data from a 30-unit sample taken from one wafer lot. The Gaussian curve is calculat- ed for the measured data’s mean and standard deviation and is scaled to account for process variations (the listed mean and standard deviation are from the scaled distribution, as plotted). GAIN (+85° ...

... The part’s con- version gain has been specified with the resistors in place (using the output network on the MAX2690 EV kit), accounting for a 3dB loss due to the resistors. Therefore, RF Input it is possible to achieve an increase in gain with a proper- ly designed matching network ...

... SHDN pin. A series inductor is typically connected from LGND to GND. Adjusting the value of this inductor allows the MAX2690 to be set to the optimum gain and linearity RF Input point for a particular application. A short from LGND to ground provides maximum linearity. Increasing the induc- tor value trades off linearity for gain ...
