digitally controlled analog phase shifters series qq 8,10,or 12 bits general information kdi/triangle corp.digitally controlled phase shifters vary the phase of a microwave signal in response to a ttl compatible logic input signal. the unit consists of an analog phase shifter, series pq, plus a digital to analog converter.(see figure 1) a balanced stripline configuration keeps the vswr and amplitude change to a minimum for all values of phase. standard units operate with 8 bits all owing 256 discrete values of phase.if 10 bits are required add ?0 to model no.(e.g., qq-12-10).if 12 bits are required add ?2 to model no.(e.g., qq-12-12). general specifications frequency c o verage: 0.1 to 18.0 ghz rf impedance: 50 ohms. rf power: 10 mw peak or cw , operating.destruct level is 1 w, cw, 100 w peak. temperature information:the units can be used ov er a ?5 c to +85 c temper ature range.how ever, the phase will change either 5 or 5%, whichever is greater.if temper ature com- pensation is required, this can be done on request.with compensation, the var i- ation can be held to ? or ?%, whichever is greater , from ?5 c to +85 c.compensation increases the cost by 10%.the size remains the same.if compensation is desired, add a suffix t to the model n umber, e.g.(qq-17t). connectors: sma.mating m ultipin connector is sup- plied with each unit;itt cannon da-15s or equiv. notes: 1.the voltages required are 615 volts at 50 ma. 2.switching speed of all models is 200 nanosec.higher speeds on request.for 12 bits speed is 2 microsec. 3.monotonicity is guaranteed for all models. 4.phase flatness:the phase shift varies with frequency at any v olt- age setting.this variation, referred to 0 at logic 0 f or each fre- quency, is approximately 6 15% for octave models, 6 10% for models with 25% bandwidth, and 67.5% for models with a 10% bandwidth. 5.in order to determine the step size (least significant bit) of any phase shifter, divide the listed value of phase shift by the number of steps. a b c d e f in in in in in in outline [mm] [mm] [mm] [mm] [mm] [mm] 1 5.00 2.00 n/a 1.800 4.500 0.50 [127,0] [50,8] 4 holes [45,7] [114,3] [12,7] 2 7.75 2.50 n/a 2.300 7.250 0.75 [196,9] [63,5] 4 holes [58,42] [184,15] [19,1] 3 6.50 2.00 n/a 1.800 6.000 0.25 [165,1] [50,8] 4 holes [45,7] [152,4] [6,4] 4 3.00 2.00 1.50 1.800 2.500 0.30 [76,2] [50,8] [38,1] [45,7] [63,5] [7,6] 5 7.75 2.50 n/a 2.300 7.250 0.25 [196,9] [63,5] 4 holes [58,42] [184,15] [6,4] 6 5.00 2.00 n/a 1.800 4.500 0.25 [127,0] [50,8] 4 holes [45,7] [114,3] [6,4] phase shift insertion amplitude fr equency note 4 loss ripple model range minimum maximum maximum vswr out- no. ghz degrees db ?b maximum line qq-12 0.1?.2 45 0.6 0.15 1.35 4 qq-16 0.25?.5 45 0.6 0.15 1.35 4 qq-17 0.25?.5 360 4.5 1.25 1.70 2 qq-27 0.5?.0 180 3.0 0.40 1.50 1 QQ-28 0.5?.0 360 4.5 1.25 1.75 5 qq-34 1.0?.0 360 4.5 1.50 1.80 5 qq-44 2.0?.0 180 3.0 0.50 1.60 6 qq-45 2.0?.0 360 5.0 1.50 1.90 3 qq-60 4.0?.0 360 8.0 1.50 1.90 1 qq-65 6.0?8.0 180 12.0 2.0 2.50 4 qq-66 7.0?2.4 360 12.0 2.0 2.20 1 qq-72 8.0?2.4 60 2.0 0.25 1.75 4 qq-73 8.0?0.0 180 4.5 1.0 1.75 4 qq-74 8.0?8.0 360 17.0 3.5 2.50 1 qq-94 16.0?7.0 45 2.0 0.20 1.65 4 pin* function 1?2 logic inputs 13 +15 vdc 14 ?5 vdc 15 gnd rf rf +15 ?5 fig. 1 analog phase shifter d/a converter mechanical outlines electrical performance c sma female typ. b d power/logic note: either rf connector may be used for input 0.38[2.65] typ. 0.125[3,18] dia. thru 3 mtg. holes 0.10[2,5] pin 9 pin 1 itt cannon da-15p or equiv. 0.25[6,4] a e rf 0.19 [4,826] 1.00 [25,4] f qq-49 2.2?.3 180 2.0 0.30 1.50 6 # bits # steps 8 256 10 1024 12 4096 figure 1 power logic pin connections *pin 1 is least significant bit key: inches[millimeters] .xx ?03 .xxx ?010 [.x ?.8 .xx ?.25] 8-10-07 60 south jefferson road, whippany, nj 07981 tel: 973-887-8100 ?fax: 973-884-0445 email: sales@aeroflex-kdi.com see us on the web @ www.aeroflex-kdi.com
