max2320/21/22/24/26/27 adjustable, high-linearity, sige dual-band lna/mixer ics ______________________________________________________________________________________ 15 detailed description low-noise amplifier within its operating bands, each device in the max2320 family (except the max2327) has three modes of lna operation: high gain, high linearity (hghl); high gain, low linearity (hgll); and low gain, high linearity (lghl). the logic inputs control the lna mode as described in the ac electrical characteristics . use hghl mode when extra-high lna linearity is required for cross-modulation suppression. use hgll mode when the transmitter is off and cross-modulation is not a concern. when the lna changes modes, the input vswr change is minimal. use lghl mode for receiving large signals and when high sensitivity is not required. the max2327 lna has only an hgll mode. adjust the hghl mode lna linearity by changing r rlna , and adjust linearity of the other modes by changing r rbias . 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 band fm mixer has its own if output to feed a different filter. adjust the downconverter linearity and current by changing r rbias (see typical operating character- istics ). when the linearity requirement is high, the mode control inputs increase the current in the downconvert- er. when the linearity requirement is not high, the cur- rent is lower. lo output buffers the buffen logic input turns the open-collector lo output buffers on and off. this feature saves current if the buffers are not required. operational modes each device has logic input pins that control the differ- ent operational modes listed in tables 1?. max2320/max2321/max2326 operation the max2320/max2321/max2326 are dual-band, triple- mode receivers that amplify and downconvert cellular- and pcs-band signals. they consist of cellular and pcs lnas; cellular digital, cellular fm, and pcs digital mix- ers; and cellular and pcs lo buffers. the max2321 has an lo frequency doubler on-chip, so a single cellular- band vco can be used for both the cellular- and pcs- band mixers. selecting the pcs path activates the lo frequency doubler. the max2326 has an lo divide-by- two circuit, so a single pcs-band vco can be used for both the cellular and pcs mixers. selecting the cellular path activates the lo divide-by-two circuit. three logic input pins band , gain, and lin?ontrol eight opera- tional modes of the lnas and mixers. the modes are summarized in table 1. table 1. max2320/max2321/max2326 operational modes note: l = logic low; h = logic high band shutdown. the entire part is shut down except for the lo buffer, which is con- trolled by buffen. l description gain l lin l low-gain, high-linearity (lghl) pcs mode. the pcs lna and mixer are in lghl mode. l l h high-gain, low-linearity (hgll) pcs mode. the lna and mixer are in hgll mode. l h l high-gain, high-linearity (hghl) pcs mode. the lna and mixer are in hghl mode. l h h high-gain, low-linearity (hgll) cellular fm mode. the cellular lna is in hgll mode. the fm mixer and associated lo buffer are selected. h l l low-gain, high-linearity (lghl) cellular digital mode. the cellular lna and mixer are in lghl mode. h l h high-gain, low-linearity (hgll) cellular digital mode. the cellular lna and mixer are in hgll mode. h h l high-gain, high-linearity (hghl ) cellular digital mode. the cellular lna and mixer are in hghl mode. h h h
