Notes:
1. Cj is measured at VR = 0V and f = 1.0 MHz.
2. V
F is measured at IF = 1.0 mA.
3. Series Resistance, R
s, is determined by subtracting the junction
resistance Rj, from the measured value of 10 mA dynamic (slope)
resistance, R
T:
R
s = RT - Rj ohms
Junction resistance is computed from:
Rj = 26/l
F
I
F = 10 mA
I
F is the forward current in mA
4. Noise gure measurements are single sideband noise gure with N
IF =
1.5 dB minimum. The noise gure of chips and beam lead types are
performed on a sample of the lot. Chips are tested in a package. Beam
leads are tested in a stripline holder The test conditions are as follows:
LO Power

5. V
R is measured at lR = 10 A.
6. C
j is measured at VR = 0V and f = 1.0 MHz. Cj of anti-parallel diodes is
comprised of the capacitance of two diode junctions in parallel.
7. C
j is measured between adjacent leads of device at VR = 0V and
f = 1 MHz.
8. C
T = Cj + CP
C
T is total capacitance
C
j is junction capacitance
C
P is packaged capacitance
9. Conversion loss at 94 GHz with LO power ~ 8-12 dBm.
10. The part number includes the case style as a sufx. i.e. MA40418 -
1169 is a beam-lead Tee; MA40418-963 is the part in the
case style 963.
