6 vmmk-3313 biasing information biasing and operation the vmmk-3313 is a 3 terminal device consisting of a through 50 ohm line connecting directly between the rf input and rf output ports and a directional coupler with a full wave detector that provides a dc output proportional to rf power input. as with any high frequency device, good grounding is required on the common port under the device for it to produce low loss in the through mode. a suggested pcb layout with appropriate grounding will be cover later in this application section. with only 3 terminals available, the dc bias and detected voltage are internally dc coupled to the input and output terminals respectively. the key to successful operation of the vmmk-3313 is the use of low loss bias decoupling networks connected to both the rf input and the rf output ports. figure 7 shows a simple biasing circuit. the bias decoupling networks provide a low loss ac coupled rf path to the device, a means of biasing the device on the input, and a means of extracting the detected voltage on the output of the device. the detector needs 2 dc blocking caps, c1 and c2, on the input and output ports. this can be accomplished by printing coupled lines on the pcb or using smt capacitors (atc 600 series) with bias detector r1 c1 r2 c2 c4 r3 vdet vb c3 rfin rfout component description c1, c2 0.2 pf to 0.4 pf (atc 600 or printed coupled lines) r1 (vb -1.5) / 0.00014 ? r2 10 k ? c3, c4 1 pf r3 external load resistor (optional) figure 7. biasing the vmmk-3313 detector module values chosen for the frequency of operation. all smt components are recommended to be no larger than 0402 size. nominal bias voltage of 1.5 v or 0.14 ma is required for proper operation. biasing on the input is by a way of a large value resistor r1. its value can be computed using the following equation: r1 = (vb -1.5)/0.00014 where vb is the supply voltage. detected dc voltage is extracted on the output by a way of a large value resistor r2, in the range of 10 k ? . bypassing capacitors c3 and c4 are needed to prevent rf infuence on the dc lines. suggested value for bypass capacitors is 1 pf. at zero rf input power, and at 1.5 v supply bias, a nominal 63 mv ofset voltage appears at the detected output port. the internal output source resistance for the detector is approximately 20 k ? . resistor r3 can be used as an external load resistor for the detector. its value can be optimized for the desired vout vs. rf input curve. figure 8 shows a vmmk-3313 characterization pcb used to obtain the vdet vs. input power characterization data from 15 to 33 ghz. for ease in broadband characteriza - tion, two external 45 mhz C 50 ghz bias networks (hp 11612b) were used. figure 8. vmmk-3313 characterization board
7 s parameter measurements the s-parameters are measured on a 0.016 inch thick ro4003 printed circuit test board, using 300 m m g-s-g (ground signal ground) probes. coplanar waveguide is used to provide a smooth transition form the probes to the device under test. the presence of the ground plane on top of the test board results in excellent grounding at the device under test. a combination of solt (short C open C load C thru) and trl (thru C refect C line) cali - bration techniques are used to correct for the efects of the test board, resulting in accurate device s parameters. package and assembly notes for detailed description of the device package and assembly notes, please refer to application note 5378. package dimension outline reel orientation device orientation dimensions symbol min (mm) max (mm) e 0.500 0.585 d 1.004 1.085 a 0.225 0.275 not e: all dimensions ar e in mm a e d top view end view ? ty ? ty ? ty ? ty 8 mm 4 mm user feed direction notes: ?t? = device code ?y? = month code esd precautions note: these devices are esd sensitive. the following pre - cautions are strongly recommended. ensure that an esd approved carrier is used when die are transported from one destination to another. personal grounding is to be worn at all times when handling these devices. for more detail, refer to avago application note a004r: electro- static discharge damage and control. ordering information part number devices per container container vmmk-3313-blkg 100 antistatic bag vmmk-3313-tr1g 5000 7 reel vmmk-3313-tr2g 1000 7 reel user feed direction carrier tape reel
