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 the application section. 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 0.16 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: 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-3413 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. Detected DC voltage is extracted on the output by a way of a large value resistor R2, in the range of 10 kΩ. Bypassing capacitors C3 and C4 are needed to prevent RF influence on the DC lines. Suggested value for bypass capacitors is 1 pF. 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 C1 C2 RFin where Vb is the supply voltage. At zero RF input power, and at 1.5 V supply bias, a nominal 63 mV offset voltage appears at the detected output port. The internal output source resistance for the detector is approximately 20 kΩ. 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 characterization PCB used to obtain the Vdet vs. Input Power characterization data from 25 to 45 GHz. For ease in broadband characterization, two external 45 MHz – 50 GHz Bias Networks (HP 11612B) were used.

VMMK-3413 Characterization Board S Parameter Measurements ESD Precautions The S-parameters are measured on a 0.016 inch thick RO4003 printed circuit test board, using 300 mm 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 – Open – Load – Thru) and TRL (Thru – Reflect -–Line) calibration techniques are used to correct for the effects of the test board, resulting in accurate device S parameters Note: These devices are ESD sensitive. The following precautions 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.
