Additional Details

The PE4135 SPDT switch utilizes a monolithic silicon-on-insulator (SOI) process to achieve optimal performance. It is designed for both broadband and narrowband applications, and is suitable for use in systems operating from DC to 8 GHz. The switch is controlled by a single control voltage, making it easy to integrate into existing designs. The SMT package is compatible with standard surface mount assembly techniques, reducing manufacturing costs and time. The switch offers a typical insertion loss of 0.6 dB at 4 GHz and isolation of 30 dB at 4 GHz. The switching speed is typically 20 ns. It operates over a temperature range of -40°C to +85°C.

The PE4135 is supplied in a small 6-lead surface-mount package, allowing for high-density circuit designs. The switch requires a positive control voltage to operate, typically between +3V and +5V. This device provides a cost-effective solution for high-performance RF switching applications.
