VMMK-3413 Biasing Information

Biasing and Operation

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.

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) cali-

bration techniques are used to correct for the effects of

the test board, resulting in accurate device S parameters
