sige high-linearity, 2000mhz to 3000mhz upconversion/downconversion mixer with lo buffer max2042 24 _____________________________________________________________________________________ detailed description when used as a low-side lo injection mixer in the 2300mhz to 2900mhz band, the max2042 provides +36dbm of iip3, with typical noise figure and conver - sion loss values of only 7.3db and 7.2db, respectively. the integrated baluns and matching circuitry allow for 50 i single-ended interfaces to the rf and the lo ports. the integrated lo buffer provides a high drive level to the mixer core, reducing the lo drive required at the max2042s input to a -3dbm to +3dbm range. the if port incorporates a differential interface, which is ideal for providing enhanced 2rf-2lo performance. specifications are guaranteed over broad frequency ranges to allow for use in wcs, lte, wimax, and mmds base stations. the max2042 is specified to operate over an rf input range of 2000mhz to 3000mhz, an lo range of 1800mhz to 2800mhz, and an if range of 50mhz to 500mhz. the external if transformer sets the lower fre - quency range (see the typical operating characteristics for details). operation beyond these ranges is possible (see the typical operating characteristics for additional information). rf interface and balun the max2042 rf input provides a 50 i match when combined with a series dc-blocking capacitor. this dc-blocking capacitor required as the input is internally dc shorted to ground through the on-chip balun. when using an 8.2pf dc-blocking capacitor, the rf port input return loss is typically 15db over the rf frequency range of 2500mhz to 2900mhz. lo inputs, buffer, and balun the max2042 is optimized for low-side lo injection applications with an 1800mhz to 2800mhz lo frequency range. the lo input is internally matched to 50 i , requir - ing only a 2pf dc-blocking capacitor. a two-stage internal lo buffer allows for a -3dbm to +3dbm lo input power range. the on-chip low-loss balun, along with an lo buffer, drives the double-balanced mixer. all interfac - ing and matching components from the lo inputs to the if outputs are integrated on-chip. high-linearity mixer the core of the max2042 is a double-balanced, high- performance passive mixer. exceptional linearity is pro - vided by the large lo swing from the on-chip lo buffer. iip3, 2rf-2lo rejection, and noise-figure performance are typically +36dbm, 70dbc, and 7.3db, respectively. differential if interface the max2042 has an if frequency range of 50mhz to 500mhz, where the low-end frequency depends on the frequency response of the external if components. the max2042s differential ports are ideal for provid - ing enhanced 2rf-2lo performance. the user can use a differential if amplifier or saw filter on the mixer if port, but a dc block is required on both if+/if- ports to keep external dc from entering the if ports of the mixer. typical applications typically use a 1:1 transformer such as the mabaes0029 to transform the 50 i differential interface to a 50 i single-ended interface. the loss of this transformer is included in the data presented in this data sheet. in addition, the if interface directly supports single-ended ac-coupled signals into or out of if+ by shorting if- to ground, and a 1k i resistor from if+ to ground. applications information input and output matching the rf input provides a 50 i match when combined with a series dc-blocking capacitor. use an 8.2pf capaci - tor value for rf frequencies ranging from 2000mhz to 3000mhz. the lo input is internally matched to 50 i ; use a 2pf dc-blocking capacitor to cover operations spanning the 1800mhz to 2800mhz range. the if output impedance is 50 i (differential). for evaluation, an exter - nal low-loss 1:1 (impedance ratio) balun transforms this impedance down to a 50 i single-ended output (see the typical application circuit ). reduced-power mode the max2042 has one pin (lobias) that allows an exter - nal resistor to set the internal bias current. a nominal value for this resistor is shown in tables 1 and 2. larger value resistors can be used to reduce power dissipa - tion at the expense of some performance loss. see the typical operating characteristics to evaluate the power vs. performance tradeoff. if q 1% resistors are not readily available, substitute with q 5% resistors. significant reductions in power consumption can also be realized by operating the mixer with an optional supply voltage of +3.3v. doing so reduces the overall power consumption by up to 43%. see the +3.3v supply ac electrical characteristics table and the relevant +3.3v curves in the typical operating characteristics section to evaluate the power vs. performance tradeoffs.
