The CLA4611-085LF is a surface mountable, low capacitance
silicon PIN limiter diode designed as a shunt connected PIN diode
for high power limiter applications from 10 MHz to over 6 GHz.
Maximum resistance at 10 mA is 1.2 Ω and maximum
capacitance at 38 V is 0.25 pF (typical). The combination of low
junction capacitance, low parasitic inductance, low thermal
resistance, and nominal 12 μm I-region width, makes the
CLA4611-085LF useful in large signal limiter applications. The
threshold level is +25 dBm, nominal.
A block diagram of the CLA4611-085LF is shown in Figure 1. The
absolute maximum ratings of the CLA4611-085LF are provided in
Table 1. Electrical specifications are provided in Table 2.
Typical performance characteristics of the CLA4611-085LF are
provided in Table 3 and illustrated in Figure 4.
