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.
