* Case styles are specified by adding the case style number as a suffix to
the basic part number. For example, an MA4E402L-228 is a low barrier
bridge quad housed in the 228 case style. The available packages are
226, 227, 228 or 963. To order a beam lead part add “- 906”.
Notes:
1. C
j is measured across diagonal leads at VR = 0V and f = 1 MHz.
2. C
T = Cj + CP is the package capacitance.
3. Series resistance, R
S, is determined by subtracting the junction
resistance, Rj, from the measured value of 10 mA dynamic (slope)
resistance, RT:
R
S = RT - Rj Ohms
Junction resistance is computed from the following equation:
R
j = 26/1F Ohms
I
F is the forward bias current in mA.
4.
C
j is measured across adjacent quad leads at VR = 0V and
f = 1 MHz.
5. V
R is measured at IR = 10 A
Applications
These beam lead Schottky bridge quads are commonly
used in sampling and modulator applications. The small
case sizes and minimal electrical parasitics are well suited
for miniature broadband components.
High speed switching, a necessary sampling requirement,
is accomplished with the Schottky diode. Schottky diodes
have switching speeds in the picosecond range. The four
closely matched junctions assure high inherent isolation
between the signal and sampler pulse circuits.
The different barrier heights enable the designer to select
a diode with an appropriate barrier such that the RF sig-
nal input to the sampler will not cause the diodes in the
bridge to conduct. The diode circuit configuration is
shown on the next page.
