Description
The CLA4605-085LF 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 2 Ω and maximum capacitance
at 6 V is 0.45 pF. The combination of low junction capacitance,
low parasitic inductance, low thermal resistance, and nominal
2 um I-region width, makes the CLA4605-085LF useful in large
signal limiter applications. The threshold level is +9 dBm,
nominal.
A block diagram of the CLA4605-085LF is shown in Figure 1. The
absolute maximum ratings of the CLA4605-085LF are provided in
Table 1. Electrical specifications are provided in Table 2.
Typical performance characteristics of the CLA4605-085LF are
provided in Table 3 and illustrated in Figures 4 and 5.
