general description the max2338 receiver rf front-end ic is designed for dual-band cdma cellular phones and can also be used in dual-band tdma, gsm, or edge cellular phones. thanks to the max2338? on-chip low-power lo divider, the cellular vco module can be eliminated. the max2338 includes a low-noise amplifier (lna) with an adjustable high-input third-order intercept point (iip3) to minimize intermodulation and cross-modulation in the presence of large interfering signals. for cellular band operation, a low-gain lna is available for higher cascaded iip3 at lower current. the cdma mixers are designed for high linearity, low noise, and differential if outputs. the fm mixer is designed for lower current and single-ended output. the max2338 triple-mode lna/mixer includes an on- chip lo frequency divider to allow the use of a single vco for both bands. this device is available in an ultra- small 28-pin leadless qfn package. ________________________applications dual-band, triple-mode pcs/cellular phones dual-mode cellular phones features 1.4db lna noise figure 15db lna gain mixer noise figure 7.5db (cdma) 8.7db (amps) mixer gain 14.5db pcs 13.3db cellular 8.8db amps lo frequency divider, saves vco module lo output buffers for tx ultra-small 28-pin leadless package max2338 triple/dual-mode cdma lna/mixers ________________________________________________________________ maxim integrated products 1 max2338 25 26 27 28 22 23 24 8 9 10 11 12 13 14 15 16 17 18 19 20 21 1 2 3 4 5 6 7 n.c. gnd lo/2 loin gnd ploout cloout cmixin clnaout gnd plnaout gnd gnd pmixin gnd clnain lin gain plnain rlna if- gnd buffen v cc fmout if+ rbias qfn top view 2 band 19-1807; rev 2; 4/03 e v a l u a t i o n k i t a v a i l a b l e ordering information 28 qfn pin-package temp range -40? to +85? max2338egi part pin configuration/ functional diagram typical operating circuit appears at end of data sheet. for pricing, delivery, and ordering information, please contact maxim/dallas direct! at 1-888-629-4642, or visit maxim? website at www.maxim-ic.com.

max2338 triple/dual-mode cdma lna/mixers _______________________________________________________________________________________ 9 detailed description the max2338 consists of cellular band and pcs band (lnas) and mixers. the ic also consists of a local oscillator (lo) divider and lo buffers for cellular and pcs bands. low-noise amplifiers the max2338 lnas gain and linearity are switched by the gain and lin input, respectively. the pcs band lna has two operational modes: high-gain high-linearity (hghl) and high-gain low-linearity (hgll). the cellular band lna has three operational in modes: hghl, hgll, and low-gain high-linearity (lghl) modes. the table in the operational modes section shows the pin settings for band , gain, and lin for various operating modes. use hghl mode when extra high linearity is required for cross-modulation suppression, hgll mode when the transmitter is off and cross-modulation is not a concern, and lghl mode when receiving large signals. downconverter the downconverters in these devices are double bal- anced mixers. the pcs band mixer and digital cellular band mixer share the same if output ports. the cellular fm band mixer has its own if output to feed to a different filter. when the linearity requirement is high, the lin con- trol input increases the current in the downconverter. the downconverter requires a dc blocking capacitor at the input and output, and a pullup inductor at the output. the dc blocking capacitors can be designed to be part of the matching circuits. the table in the operational modes section shows the settings for band , gain, and lin for various operating modes. lo output buffers there are two lo output buffers: cellular and pcs. the inputs are tied together and internally matched to 50 ? . the outputs of the pcs and cellular buffers are brought out separately. the outputs of the buffers are internally matched and include a dc blocking capacitor. lo divider the max2338 includes an lo divider circuit which enables a single vco for both cellular and pcs bands. the lo/2 logic input turns the divider on or off in the cel- lular band. function control pin modes band (h/l) lox1 lo /2 hghl amp hgll amp lghl amp cdma hl mixer cdma ll mixer fm mixer band gain lin lo/2 pcs band, high-gain, high-linearity (hghl) h 011 x pcs band, high-gain, low-linearty (idle mode) (hgll) h 010 x undefined 001 x cellular band cdma, high-gain, high-linearity (hghl) l 111 1 cellular band cdma, high-gain, low-linearity (idle mode) (hgll) l 110 1 cellular band, cdma, low-gain l 101 1 cellular band, fm mode l 100 1 cellular band cdma, high-gain, high-linearity (hghl) l 111 0 cellular band cdma, high-gain, low-linearity (idle mode) (hgll) l 110 0 cellular band, cdma, low-gain l 101 0 cellular band, fm mode l 100 0 shutdown 000 x table 1. operational modes
