The CLA4609-086LF 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 100 mA is 1.5 Ω and maximum
capacitance at 30 V is 0.6 pF. The combination of low junction
capacitance, low parasitic inductance, low thermal resistance,
and nominal 28 μm I-region width, makes the CLA4609-086LF
useful in large signal limiter applications. The threshold level is
+36 dBm, nominal.
A block diagram of the CLA4609-086LF is shown in Figure 1. The
absolute maximum ratings of the CLA4609-086LF are provided in
Table 1. Electrical specifications are provided in Table 2.
Typical performance characteristics of the CLA4609-086LF are
provided in Table 3 and illustrated in Figure 4.
