| 1 for more information www.linear.com/LTC5510 typical a pplica t ion fea t ures descrip t ion 1mhz to 6ghz wideband high linearity active mixer the lt c ? 5510 is a high linearity mixer optimized for applica - tions requiring very wide input bandwidth, low distortion, and low lo leakage. the chip includes a double-balanced active mixer with an input buffer and a high speed lo ampli - fier. the input is optimized for use with 1:1 transmission- line baluns, allowing very wideband impedance matching. the mixer can be used for both up- and down-conversion and can be used in wideband systems. the lo can be driven differentially or single-ended and requires only 0 dbm of lo power to achieve excellent distor - tion and noise performance, while also reducing external drive circuit requirements. the LTC5510 offers low lo leakage, greatly reducing the need for output filtering to meet lo suppression requirements. the LTC5510 is optimized for 5 v but can also be used with a 3.3 v supply with slightly reduced performance. the shutdown function allows the part to be disabled for further power savings. 30mhz to 4ghz up/down mixer for wideband receiver conversion gain, iip3 and nf vs input frequency a pplica t ions n input/lo frequency range to 6ghz n 50 matched input from 30mhz to >3ghz n capable of up- or down-conversion n oip3: 27dbm at f out = 1575mhz n 1.5db conversion gain n noise figure: 11.6db at f out = 1575mhz n high input p1db: 11dbm at 5v n 5v or 3.3v supply at 105ma n shutdown control n lo input impedance always matched n 0dbm lo drive level n 0n-chip temperature monitor n C40c to 105c operation (t c ) n 16-lead (4mm 4mm) qfn package n wideband receivers/transmitters n cable downlink infrastructure n hf/vhf/uhf mixer n wireless infrastructure l, lt , lt c , lt m , linear technology and the linear logo are registered trademarks of linear technology corporation. all other trademarks are the property of their respective owners. lgnd lo ? lo + temp temperature monitor out + out ? in + in ? 10nf en en v cc1 v cc2 i adj 5v LTC5510 1f 6.8nh 6.8nh 5510 ta01 lo 50 out 1575mhz 50 bd1222j50200ahf 4:1 in 30mhz to 4ghz 50 tcm1-43x + 1:1 0.1f 0.1f 0.1f 0.1f 0.6pf 6.8pf 10nf 4.75k bias input frequency (mhz) 0 gain (db), iip3 (dbm), nf (db) 20 25 15 10 1000 3000 2000 4000 5 0 30 5510 ta01a g c iip3 f out = 1575mhz p in = ?10dbm p lo = 0dbm t c = 25c nf hs lo ls lo 5510f ltc 5510

LTC5510 evaluation board layouts 3a. high frequency output board (dc1983a) 3b. low frequency output board (dc1984a) external components required for the data sheet specified performance are shown in figures 1 and 2. the evaluation boards are shown in figures 3a and 3b. the high frequency output test circuit, shown in figure 1, utilizes a multilayer chip balun to realize a single-ended output. the low frequency output test circuit in figure 2 uses a wire-wound balun and is designed to accommodate a differential output if desired. both the in and lo ports are very broadband and use the same configurations for both test circuits. additional components may be used to modify the dc supply current or frequency response, which will be discussed in the following sections. in port interface a simplified schematic of the mixer s input is shown in figure 4 a . the in + and in C pins drive the bases of the input transistors while internal resistors are used for impedance matching. these pins are internally biased to a common mode voltage of 1.6v , thus external capacitors c 1 and c2 are required for dc isolation and can be used for impedance matching. a small value of c 3 can be used to improve the impedance match at high frequencies and may improve noise figure. the 1:1 transformer, t 1, provides single- ended to differential conversion for optimum performance . the typical return loss at the in port is shown in figure 5 with 0.1 f at c1 and c2. the performance is better than 12db up to 2.6 ghz without c3. adding a capacitance of 0.7pf at c3 extends the impedance match to 3ghz. differential input impedances ( parallel equivalent) for various frequencies are listed in table 1. at frequencies below 30 mhz additional external components may be needed to optimize the input impedance. figure 4 b shows an equivalent circuit that can be used for single-ended or differential impedance matching at frequencies below 1ghz. above 1ghz, the s-parameters should be used. the dc bias current of the input amplifier flows through pin 4 ( lgnd). typically this pin should be directly connected to a good rf ground; however, at lower input frequencies it may be beneficial to insert an inductor to ground for improved ip2 performance. the inductor should have low resistance and must be rated to handle 64 ma dc current. 5510 f03a 5510 f03b 5510f ltc 5510 18 for more information www.linear.com/LTC5510 a pplica t ions i n f or m a t ion figure 4a. in port with external matching figure 4b. in port equivalent circuit (< 1ghz) v cc 5510 f04a in 50 t1 1:1 2 3 c1 LTC5510 c3 c2 64ma lgnd in + in ?
