max19997a dual, sige high-linearity, 1800mhz to 2900mhz downconversion mixer with lo buffer ______________________________________________________________________________________ 29 detailed description the max19997a dual, downconversion mixer provides high linearity and low noise figure for a multitude of 1800mhz to 2900mhz base-station applications. the device fully supports both low-side and high-side lo injection architectures for the 2300mhz to 2900mhz wimax, lte, wcs, and mmds bands. wcdma, cdma2000, and pcs1900 applications utilizing high- side lo injection architectures are also supported by adding one additional tuning element (a shunt inductor) on each rf port. the max19997a operates over an lo range of 1950mhz to 3400mhz and an if range of 50mhz to 550mhz. integrated baluns and matching circuitry allow 50 single-ended interfaces to the rf and lo ports. the integrated lo buffer provides a high drive level to the mixer core, reducing the lo drive required at the max19997a? input to a range of -3dbm to +3dbm. the if port incorporates a differential output, which is ideal for providing enhanced 2rf - 2lo (low-side injection) and 2lo - 2rf (high-side injection) performance. rf input and balun the max19997a? two rf inputs (rfmain and rfdiv) provide a 50 match when combined with a series dc- blocking capacitor. this dc-blocking capacitor is required as the input is internally dc shorted to ground through each channel? on-chip balun. when using a 22pf dc-blocking capacitor, the rf port input return loss is typically 15db over the rf frequency range of 2600mhz to 2900mhz. pin description pin name function 1 rfmain main channel rf input. internally matched to 50 . requires an input dc-blocking capacitor. 2, 5, 6, 8, 12, 15, 18, 23, 28, 31, 34 gnd ground. not internally connected. ground these pins or leave unconnected. 3, 7, 20, 22, 24?7 gnd ground. internally connected to the exposed pad. connect all ground pins and the exposed pad (ep) together. 4, 10, 16, 21, 30, 36 v cc power supply. connect bypass capacitors as close as possible to the pin (see the typical application circuit ). 9 rfdiv diversity channel rf input. internal matched to 50 . requires a dc-blocking capacitor. 11 ifd_set if diversity amplifier bias control. connect a resistor from this pin to ground to set the bias current for the diversity if amplifier. 13, 14 ifd+, ifd- diversity mixer differential if output. connect pullup inductors from each of these pins to v cc (see the typical application circuit ). 17 lo_adj_d lo diversity amplifier bias control. connect a resistor from this pin to ground to set the bias current for the diversity lo amplifier. 19 lo local oscillator input. this input is internally matched to 50 . requires an input dc- blocking capacitor. 29 lo_adj_m lo main amplifier bias control. connect a resistor from this pin to ground to set the bias current for the main lo amplifier. 32, 33 ifm-, ifm+ main mixer differential if output. connect pullup inductors from each of these pins to v cc (see the typical application circuit ). 35 ifm_set if main amplifier bias control. connect a resistor from this pin to ground to set the bias current for the main if amplifier. ?p e xp osed p ad . inter nal l y connected to gn d . s ol d er thi s exp osed p ad to a p c b p ad that uses m ul ti p l e g r ound vi as to p r ovi d e heat tr ansfer out of the d evi ce i nto the p c b g r ound p l anes. these m ul ti p l e g r ound vi as ar e al so r eq ui r ed to achi eve the noted rf p er for m ance.
max19997a dual, sige high-linearity, 1800mhz to 2900mhz downconversion mixer with lo buffer 30 ______________________________________________________________________________________ the max19997a? rf range can be further extended down to 1800mhz by adding one additional tuning ele- ment on each rf port. for 1950mhz rf applications, connect a 12nh shunt inductor from pins 1 and 9 to ground. also, change the value of the dc-blocking capacitors (c1 and c8) from 22pf to 1pf. see the typical application circuit for details. lo input, buffer, and balun a two-stage internal lo buffer allows a wide input power range for the lo drive. all guaranteed specifica- tions are for an lo signal power from -3dbm to +3dbm. the on-chip low-loss balun, along with an lo buffer, drives the double-balanced mixer. all interfacing and matching components from the lo input to the if out- puts are integrated on-chip. high-linearity mixer the core of the max19997a is a pair of double- balanced, high-performance passive mixers. exceptional linearity is provided by the large lo swing from the on-chip lo buffer. when combined with the integrated if amplifiers, the cascaded iip3, 2rf-2lo rejection, and nf performance are typically +24dbm iip3, -67dbc, and 10.3db, respectively for low-side lo injection architectures covering the 2300mhz to 2900mhz band. cascaded performance levels are comparable for high-side lo injection architectures; iip3, 2lo - 2rf rejection, and nf levels are typically rated at +24dbm iip3, -73dbc, and 10.4db, respective- ly over the same 2300mhz to 2900mhz band. differential if output amplifier the max19997a mixers have an if frequency range of 50mhz to 550mhz. the differential, open-collector if output ports require external pullup inductors to v cc . these pullup inductors are also used to resonate out the parasitic shunt capacitance of the ic, pcb components, and pcb to provide an optimized if match at the fre- quency of interest. note that differential if outputs are ideal for providing enhanced 2rf - 2lo and 2lo - 2rf rejection performance. single-ended if applications require a 4:1 balun to transform the 200 differential output impedance to a 50 single-ended output. after the balun, voltage standing-wave ratio (vswr) is typi- cally 1.2:1. applications information input and output matching the rf and lo inputs are internally matched to 50 . no matching components are required for rf frequencies ranging from 2400mhz to 2900mhz. rf and lo inputs require only dc-blocking capacitors for interfacing. if desired, the rf band can be extended down to 1800mhz by adding two external matching compo- nents on each rf port. see the typical application circuit and table 2 for details. the if output impedance is 200 (differential). for evaluation, an external low-loss 4:1 (impedance ratio) balun transforms this impedance down to a 50 single- ended output (see the typical application circuit ). reduced-power mode each channel of the max19997a has two pins (lo_adj_ _, if_ _set) that allow external resistors to set the internal bias currents. nominal values for these resistors are shown in tables 1 and 2. larger-value resistors can be used to reduce power dissipation at the expense of some performance loss. if ?% resistors are not readily available, ?% resistors may be substituted. significant reductions in power consumption can be realized by operating the mixer with an optional supply voltage of +3.3v. doing so reduces the overall power consumption by up to 53%. see the +3.3v supply, low-side lo injection ac electrical characteristics table and the relevant +3.3v curves in the typical operating characteristics section to evaluate the power vs. performance tradeoffs. layout considerations a properly designed pcb is an essential part of any rf/microwave circuit. keep rf signal lines as short as possible to reduce losses, radiation, and inductance. for the best performance, route the ground pin traces directly to the exposed pad under the package. the pcb exposed pad must be connected to the ground plane of the pcb. it is suggested that multiple vias be used to connect this pad to the lower-level ground planes. this method provides a good rf/ther- mal-conduction path for the device. solder the exposed pad on the bottom of the device package to the pcb. the max19997a evaluation kit can be used as a refer- ence for board layout. gerber files are available upon request at www.maxim-ic.com .
